Factors of 4900 by Prime Factorization
- 4900 ÷ 2 = 2450
- 2450 ÷ 2 = 1225
Further dividing 1225 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 1225 by the next smallest prime factor. We stop ultimately if the next prime factor doesn't exist or when we can't divide any further.
So, the prime factorization of 4900 can be written as 22 × 52 × 72 where 2, 5, 7 are prime.

Example 1: How many factors are there for 4900?
Solution:
The factors of 4900 are too many, therefore if we can find the prime factorization of 4900, then the total number of factors can be calculated using the formula shown below.
If the prime factorization of the number is ax × by × cz where a, b, c are prime, then the total number of factors can be given by (x + 1)(y + 1)(z + 1).
Prime Factorization of 4900 = 22 × 52 × 72
Therefore, the total number of factors are (2 + 1) × (2 + 1) × (2 + 1) = 3 × 3 × 3 = 27 -
