How to find factors of a number in pair

Steps to find factors of 378 in pair

Example: Find factors of 378 in pair

Factor Pair Pair Factorization
1 and 378 1 x 378 = 378
2 and 189 2 x 189 = 378
3 and 126 3 x 126 = 378
6 and 63 6 x 63 = 378
7 and 54 7 x 54 = 378
9 and 42 9 x 42 = 378
14 and 27 14 x 27 = 378
18 and 21 18 x 21 = 378

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 378. They are called negative pair factors.

Hence, the negative pairs of 378 would be ( -1 , -378 ) .

What does factor pairs in mathematics mean?

In mathematics, factor pair of a number are all those possible combination which when multiplied together give the original number in return. Every natural number is a product of atleast one factor pair. Eg- Factors of 378 are 1 , 2 , 3 , 6 , 7 , 9 , 14 , 18 , 21 , 27 , 42 , 54 , 63 , 126 , 189 , 378. So, factors of 378 in pair are (1,378), (2,189), (3,126), (6,63), (7,54), (9,42), (14,27), (18,21).

What is the definition of factors?

In mathematics, factors are number, algebraic expressions which when multiplied together produce desired product. A factor of a number can be positive or negative.

Properties of Factors

  • Each number is a factor of itself. Eg. 378 is a factor of itself.
  • 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, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378 are exact divisors of 378.
  • 1 is a factor of every number. Eg. 1 is a factor of 378.
  • Every number is a factor of zero (0), since 378 x 0 = 0.

Steps to find Factors of 378

  • Step 1. Find all the numbers that would divide 378 without leaving any remainder. Starting with the number 1 upto 189 (half of 378). The number 1 and the number itself are always factors of the given number.
    378 ÷ 1 : Remainder = 0
    378 ÷ 2 : Remainder = 0
    378 ÷ 3 : Remainder = 0
    378 ÷ 6 : Remainder = 0
    378 ÷ 7 : Remainder = 0
    378 ÷ 9 : Remainder = 0
    378 ÷ 14 : Remainder = 0
    378 ÷ 18 : Remainder = 0
    378 ÷ 21 : Remainder = 0
    378 ÷ 27 : Remainder = 0
    378 ÷ 42 : Remainder = 0
    378 ÷ 54 : Remainder = 0
    378 ÷ 63 : Remainder = 0
    378 ÷ 126 : Remainder = 0
    378 ÷ 189 : Remainder = 0
    378 ÷ 378 : Remainder = 0

Hence, Factors of 378 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, and 378
