Webb9 mars 2024 · If we evaluate 15 3 + 17 3 + 19 3 + 24 3, it is easy to see that the smallest prime factor is 3, but it is tedious (without a calculator). What I tried to do was use the identity a 3 + b 3 = ( a + b) ( a 2 − a b + b 2) to try and find an a + b that can be factored out of the sum to yield the smallest prime number. This is what I got. WebbThe number 667 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 667. The first step is to divide the number 667 with the smallest prime factor, here it is 23. We keep dividing until it gives a non-zero remainder. 667 ÷ 23 = 29; Further dividing 29 by 23 gives a non-zero remainder.
