Question

Explain why 7×11×13+13 and 7×6×5×4×3×2×1+5 are composite numbers?​

Answer 1

Step-by-step explanation:

composite numbers are those who have other factors leaving 1 and itself

7×11×13+13=1014

7×6×5×4×3×2×1+5=5045

when their factors are taken out it has many factors leaving 1 and the number itself

hence it is a composite number....
