Question

Explain why 2x6 x7+7 and 3x5x7x13+13 composite number​

Answer 1

Step-by-step explanation:

After simplification of number we get 91 and 1378.

Factors of 91 and 1378 are:

$91 = 1, 7, 13, 91$

$1378=1, 2, 13, 26, 53, 106, 689, 1378.$

Composite numbers are the numbers which has more than 2 factors whereas Prime numbers are the numbers which has only 2 factors that is 1 and the number itself, for example, 2 has only 1 and 2 as its factors (prime) and 6 has 1,2,3,6 as its factors (composite).

Here, 91 and 1378 are composite numbers as they have more than 2 factors.
