Question

Explain whether (19 × 6 × 13 × 7 × 2 + 5 × 19) is a prime number or a composite number?

Answer 1

Step-by-step explanation:

(19 × 6 × 13 × 7 × 2 + 5 × 19)

= 19( 6×13×7×2+5)

= 19 × ( 1092+5)

= 19× 1097

given number written in the form of product of prime numbers so given number is a composite number (according to fundamental theorem of arithmetic)

so, (19 × 6 × 13 × 7 × 2 + 5 × 19) is a composite number
