HERE IS YOUR ANSWER.............

_________________________________

COMPOSITE NUMBER:
The composite numbers are the numbers which has 1 as its factor and its own.

7×3×5×2+3
3(7×5×2+1)

Hence in this sum the number 3 is repeating and we can take it as common and we can too say 3 is a composite number because it only has 1 and 3 as its factors.

All the prime numbers are composite numbers.
