Factors of 3969 by Prime Factorization
- 3969 ÷ 3 = 1323
- 1323 ÷ 3 = 441
- 441 ÷ 3 = 147
- 147 ÷ 3 = 49
Further dividing 49 by 3 gives a non-zero remainder. So we stop the process and continue dividing the number 49 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 3969 can be written as 34 × 72 where 3, 7 are prime.
