Answer 1

=7*11*13+13

=13(7*11*1+1)

=13*7*11+1

=1002

=2*3*167

As per the fundamental theorem of arithmetic, also called the unique factorization theorem or the unique-prime-factorization theorem, states that every integer greater than 1 either is a prime number itself or can be represented as the product of prime numbers and that, moreover, this representation is unique, up to (except for) the order of the factors.

Answer 2

Answer:

7x11x13+13

= 13(7x11x1+1)

= 13(77+1)

=13(78)

= 13x2x3x13

wkt, composite no.s has more than 2 factors. therefore it is a composite number.

hope it helps u....^_^
