What are the Factors of 252?

A factor is a number thatdivides the given number without leaving a remainder, so the numbers which give the remainder as 0 when divided by 252will be the factors of 252. For Example: 252÷ 2 = 126. Here we get the quotient 126and the remainder is 0. Hence 2 and 126are the factors of 252.

To find the factors of 252we have to find the numbers which when divided by 252give the remainder as 0. We will start dividing 252with Natural numbers i.e., 1, 2, 3, …. Up to 126(Half of 252). So, all the numbers which will provide the remainder as 0 will be the factors of 252. This method is known as Division Method.The table below provides the representation of the above method.

Therefore, the factors of 252are 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252.

Factors of 252by Prime Factorization

Prime factorization is a method of converting any composite number into the product of its prime factors. We will divide the number with subsequent prime numbers until we get thequotient as 1.

Division Method

• Step 1. Dividethe number 252with the smallest prime number which gives the remainder as 0.
• Step 2. After dividing 252with its smallest prime factor obtain the quotient.
• Step 3. Repeatstep 1 with the obtained quotient.

Prime factorization of 252

The smallest prime number as a factor of 252is 2. So, dividing 252by 2.

252÷ 2 = 126

Now the quotient is 126with the smallest prime factor as 2.

Now 126÷ 2 = 63

Similarly, 63÷ 3= 21
21÷ 3= 7
7 ÷ 7= 1

So, the prime factorization of 252is. 252= 2 × 2 × 3× 3× 7= 2²× 3²× 7.

Factor Tree Method

The factor tree method can be practiced as shown below

So, the prime factorization of 252is. 252= 2 × 2 × 3× 3× 7= 2²× 3²× 7.

Factors of 252in Pairs

Pair factors of a number imply two numbers whose product will provide the given number. The pair factors of 252will be the pair of numbers whose product will provide 252as result. The table shown below represents the calculation of factors of 252in pairs:

Also, the product of two negative numbers results in a positive number. So, the product of negative values of the above factors pairs will result in 252. They are known as negative pair factors. Hence, the negative factor pairs of 252would be (-1, -252), (-2, -126), (-3, -84), (-4, -63), (-6, -42), (-7, -36), (-9, -28),(-12, -21) and (-14, -18).

Important Notes

• Factors of a number can only be integers except 0.
• Prime numbers only have two factors 1 and the number itself andcomposite numbers have more than 2 factors and can be represented as the product of two prime numbers.As 252 has more than two factors, this makes it a composite number.
• As the sum of digits of 252 is 9, it is divisible by 3 as well as 9. Hence, 3 and 9 are factors of 252.
