Webb9 jan. 2024 · Following are the steps to find all prime factors. 1) While n is divisible by 2, print 2 and divide n by 2. 2) After step 1, n must be odd. Now start a loop from i = 3 to square root of n. While i divides n, print i and divide n by i, increment i by 2 and continue. 3) If n is a prime number and is greater than 2, then n will not become 1 by ... Webb28 nov. 2024 · 10^9+7 fulfills both the criteria. It is the first 10-digit prime number and fits in int data type as well. In fact, any prime number less than 2^30 will be fine in order to prevent possible overflows. How modulo is used: A few distributive properties of modulo are as follows: ( a + b) % c = ( ( a % c ) + ( b % c ) ) % c.
