Factors of 2240 by Prime Factorization
- 2240 ÷ 2 = 1120
- 1120 ÷ 2 = 560
- 560 ÷ 2 = 280
- 280 ÷ 2 = 140
- 140 ÷ 2 = 70
- 70 ÷ 2 = 35
Further dividing 35 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 35 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 2240 can be written as 26 × 51 × 71 where 2, 5, 7 are prime.
