WebbThe prime factorization of 42 is explained below: Divide the number 42 with the smallest prime factor 2. 42 ÷ 2 = 21. Check if 21 can be further divided by 2 or not. 21 ÷ 2 = 10.5. Since 21 is not completely divisible by 2, we will proceed to the next prime number, which is 3. Dividing 21 by 3, 21 ÷ 3 = 7. WebbThe largest three factors must be at least 100000007, 10007, and 101. Goto and Ohno (2006) verified that the largest factor must be at least 100000007 using an extension to …
Prove this number must be a prime number or 1.
