How to find factors of a number in pair

Steps to find factors of 490 in pair

Example: Find factors of 490 in pair

Factor Pair Pair Factorization
1 and 490 1 x 490 = 490
2 and 245 2 x 245 = 490
5 and 98 5 x 98 = 490
7 and 70 7 x 70 = 490
10 and 49 10 x 49 = 490
14 and 35 14 x 35 = 490

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 490. They are called negative pair factors.

Hence, the negative pairs of 490 would be ( -1 , -490 ) .

Definition of factor pairs?

In mathematics, factor pair are often given as pair of numbers which when multiplied together give the original number. Every natural number is a product of atleast one factor pair. Eg- Factors of 490 are 1 , 2 , 5 , 7 , 10 , 14 , 35 , 49 , 70 , 98 , 245 , 490. So, factors of 490 in pair are (1,490), (2,245), (5,98), (7,70), (10,49), (14,35).

What are factors?

In mathematics, a factor is that number which divides into another number exactly, without leaving a remainder. A factor of a number can be positive or negative.

Properties of Factors

  • Each number is a factor of itself. Eg. 490 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, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490 are exact divisors of 490.
  • 1 is a factor of every number. Eg. 1 is a factor of 490.
  • Every number is a factor of zero (0), since 490 x 0 = 0.

Steps to find Factors of 490

  • Step 1. Find all the numbers that would divide 490 without leaving any remainder. Starting with the number 1 upto 245 (half of 490). The number 1 and the number itself are always factors of the given number.
    490 ÷ 1 : Remainder = 0
    490 ÷ 2 : Remainder = 0
    490 ÷ 5 : Remainder = 0
    490 ÷ 7 : Remainder = 0
    490 ÷ 10 : Remainder = 0
    490 ÷ 14 : Remainder = 0
    490 ÷ 35 : Remainder = 0
    490 ÷ 49 : Remainder = 0
    490 ÷ 70 : Remainder = 0
    490 ÷ 98 : Remainder = 0
    490 ÷ 245 : Remainder = 0
    490 ÷ 490 : Remainder = 0

Hence, Factors of 490 are 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, and 490
