Answer 1

Step-by-step explanation:

we can write 7×11×13+13

=13(7×11+1)=13(77+1)

=13×78=13×2×39

• it shows that we can write the given number as the factors of prime number so it is a composite number
• Now 7×6×5×4×3×2×1+5
• =5(7×6×5×4×3×2×1+1)
• =5(1008+1)
• =5×(1009)
• similarly we can write given number as the factor of prime number so it is a composite number
