Factors that 42 are the perform of positive and negative whole numbers that deserve to be divided evenly into 42. An unfavorable factors of 42 space just determinants with a an unfavorable sign. The number 42 is far-reaching and is an even composite number which method that it has several factors, in this case, 42 has 8 factors. In this lesson, we will certainly calculate the factors of 42, its prime factors, and also its factors in pairs. We will certainly also shot a few solved examples to understand this subject better.

What are components of 42?
Factors that a number space the numbers which divide the offered number precisely without leaving any type of remainder. Factors that 42 room 1, 2, 3, 6, 7, 14, 21 and also 42.
How to calculation the factors of 42?
We deserve to use various methods like prime factorization and the division method to calculate the factors of 42. In element factorization, we express 42 as the product of its prime factors and also in the department method, we look for numbers that divide 42 exactly without a remainder.
Factors that 42 by prime Factorization
Prime factorization method expressing a number in regards to the product that its element factors. We can do this making use of the department method or by using a aspect tree.
Prime administrate by Division:Step 1: The number 42 is divided by the smallest prime number i beg your pardon divides 42 exactly, i.e. It pipeline a remainder 0.Step 2: The quotient is then divided by the the smallest or second smallest prime number and also the procedure continues it spins the quotient cannot be additional divided.Step 3: Let us divide 42 by the prime number 2 i.e 42 ÷ 2 = 21.Step 4: Now we should divide the quotient 21 by the next least prime number.Step 5: Since 21 is one odd number, that is not divisible by 2. Allow us try dividing the by 3 i m sorry is 21 ÷ 3 = 7.Step 6: 7 is a prime number and also we cannot divide it further.Step 7: Therefore, the prime factors of 42 are 2, 3, and also 7.
Prime factorization of 42 = 2 × 3 × 7
Prime administrate by element Tree
Since we space finding the prime determinants of 42, they will be placed as the root of our factor tree. Next, we compose a pair of components (two numbers, when multiplied, give 42) together branches.
3 and also 7 space prime numbers and also at this point, the variable tree ends. Let united state express 42 in regards to the product of its prime factors.42 = 2 × 3 × 7
Viola! We have done the prime factorization. Right here is a basic activity to try on your own. Instead of 2 × 21, if we had actually used 6 × 7, carry out you think us would gain the very same factors? have the right to you draw the element tree through 6 and 7 together the branches?
Prime factorization by Upside-Down Division
This an approach is referred to as the upside-down division because the division symbol is flipped upside down. In this method, we divide 42 through the smallest prime number 2 (if the number is odd, we begin with 3). 7 is a prime number. The is divisible only by 7. We prevent the department when us reach 1.
Therefore, 42 have the right to be expressed together a product of its prime factors together 2 × 3 × 7. Explore factors making use of illustrations and also interactive examples:
Think Tank:8 × 21 ÷ 4 = 42, walk this median 8 and also 21 ÷ 4 are factors of 42? Think!10.5 × 4 = 42, are 10.5 and 4 determinants of 42?Can a number higher than 42 it is in its factor?
Factors that 42 in Pairs
Factor pairs space the 2 numbers which, as soon as multiplied, offer the number 42.1 × 42 = 422 × 21 = 423 × 14 = 426 × 7 = 42
Therefore, the pair determinants of 42 room (1,42), (2,21), (3,14), and (6,7). Due to the fact that the product the two an unfavorable numbers is positive, i.e. (-) × (-) = (+), the element pairs of 42 also include (-1,-42), (-2,-21), (-3,-14), and (-6,-7). Yet let us emphasis on the positive components in this lesson.
We divide 42 by natural numbers and see which numbers leave a remainder 0. The number which divide 42 specifically without any remainder are the determinants of 42.
Division an approach to Find components of 42:
We check out that as soon as 42 is split by 1, 2, 3, 6, 7, 14, 21, and also 42, it pipeline no remainder. Hence, castle are determinants of 42.

Important Notes:The numbers which us multiply to acquire 42 are the determinants of 42.Factors that 42 are 1, 2, 3, 6, 7, 14, 21, and also 42.1 is a universal factor. The is a variable of all numbers. The number chin is a variable of the number together it divides chin exactly.Factor pairs space the bag of two numbers which, when multiplied, offer the number. Factor pairs of 42 space (1, 42), (2, 21), (3,14), and also (6,7).
