Steps to find factors of 396 in pair

Example: Find factors of 396 in pair

Factor Pair Pair Factorization
1 and 396 1 x 396 = 396
2 and 198 2 x 198 = 396
3 and 132 3 x 132 = 396
4 and 99 4 x 99 = 396
6 and 66 6 x 66 = 396
9 and 44 9 x 44 = 396
11 and 36 11 x 36 = 396
12 and 33 12 x 33 = 396
18 and 22 18 x 22 = 396

Since the product of two negative numbers gives a positive number, the product of the negative values of both the numbers in a pair factor will also give 396. They are called negative pair factors.

Hence, the negative pairs of 396 would be ( -1 , -396 ) .

Introduction to factor pairs

Factor pair in mathematics is defined as all factors of a given number which when written in pair and multiplied gives the original number. Every natural number is a product of atleast one factor pair. Eg- Factors of 396 are 1 , 2 , 3 , 4 , 6 , 9 , 11 , 12 , 18 , 22 , 33 , 36 , 44 , 66 , 99 , 132 , 198 , 396. So, factors of 396 in pair are (1,396), (2,198), (3,132), (4,99), (6,66), (9,44), (11,36), (12,33), (18,22).

How can we define factors?

In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.

Properties of Factors

  • Each number is a factor of itself. Eg. 396 is a factor of itself.
  • 1 is a factor of every number. Eg. 1 is a factor of 396.
  • Every number is a factor of zero (0), since 396 x 0 = 0.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Every factor of a number is an exact divisor of that number, example 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396 are exact divisors of 396.
  • Factors of 396 are 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396. Each factor divides 396 without leaving a remainder.
  • Every factor of a number is less than or equal to the number, eg. 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396 are all less than or equal to 396.

Steps to find Factors of 396

  • Step 1. Find all the numbers that would divide 396 without leaving any remainder. Starting with the number 1 upto 198 (half of 396). The number 1 and the number itself are always factors of the given number.
    396 ÷ 1 : Remainder = 0
    396 ÷ 2 : Remainder = 0
    396 ÷ 3 : Remainder = 0
    396 ÷ 4 : Remainder = 0
    396 ÷ 6 : Remainder = 0
    396 ÷ 9 : Remainder = 0
    396 ÷ 11 : Remainder = 0
    396 ÷ 12 : Remainder = 0
    396 ÷ 18 : Remainder = 0
    396 ÷ 22 : Remainder = 0
    396 ÷ 33 : Remainder = 0
    396 ÷ 36 : Remainder = 0
    396 ÷ 44 : Remainder = 0
    396 ÷ 66 : Remainder = 0
    396 ÷ 99 : Remainder = 0
    396 ÷ 132 : Remainder = 0
    396 ÷ 198 : Remainder = 0
    396 ÷ 396 : Remainder = 0

Hence, Factors of 396 are 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, and 396
