Question

explain why 7×11×13+13 and 7×6×5×4×2×1+5 are composite number​

Answer 1

Answer:

Explain why 7 x 11 x 13 + 13 and 7 x 6 x 5 x 4 x 3 x 2 x 1 + 5 are composite numbers. This number is multiple of two integers. Hence it has more than two factors. Hence it is a composite number.

Answer 2

Composite numbers are those numbers which are not prime and have factors more than one.

When we solve 7×11×13+13 we get 1014 which has factors more than one.

And

When we solve 7×6×5×4×3×2×1+5 we get 5045 which has factors more than one

So, both the numbers are composite numbers.
