Factors of 245 by Prime Factorization

Prime factorization means to express a composite number as the product of its prime factors.

To get the prime factorization of 245, we divide it by its smallest prime factor which is 5. 245 ÷ 5 = 49,Now divide 49 by its smallest prime factor. 49 ÷ 7 = 7This process goes on till we get the quotient as 1. 7 ÷ 7 = 1The prime factorization of 245 is shown below in 2 ways:

*

We stop the factor tree as we cannot branch further as 5 and 7 are prime numbers. Therefore prime factorization of 245 is 5 × 7 × 7.


The pair of numbers that multiply together to form 245 are said to be the factors of 245 in pairs.The distinct factor-pairs of 245 as (1,245), (5,49), (7, 35)We can have positive and negative factors of 245 in pairs. The negative factor-pairs of 245 are (-1,-245) ; (-5,-49) ; (-7, -35).
