Question

Explain why 7x11x13x17 + 17 is a composite number.

Answer 1

$= 7 \times 11 \times 13 \times 17 + 17 \\ \\ = 17(7 \times 11 \times 13 + 1) \\ = 17(77 \times 13 + 1) \\ = 17(1001 + 1) \\ = 17(1002) \\ = 17 \times 2 \times 3 \times 167 \\ = 2 \times 3 \times 17 \times 167$
so the number is composite number,because it can be represented as more than one prime factors.
