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

How do you explain factors?

In mathematics, the term factor is a number or an algebraic expression that divides another number or an expression completely without leaving any 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.
2 is the only even prime factor any number can have.
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 the common and smallest natural factor every number can have.
Every number is a factor of zero (0), since 490 x 0 = 0.
