Factors of 9800 by Prime Factorization
- 9800 ÷ 2 = 4900
- 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 9800 can be written as 23 × 52 × 72 where 2, 5, 7 are prime.
