Q12 of 104 Page 1

Explain why 7 x 11 x 13 x 17 +17 is a composite number.

Composite number: A whole number that can be divided exactly by numbers other than 1 or itself.


Given 7 x 11 x 13 x 17 +17
17 (7 x 11 x 13 x 17 +1)


17 (7 x 11 x 13 x 17 +1)


17 (17017 + 1)


17 (17018)


17 (2 × 8509)


17 × 2 × 8509


So, given number is the composite number because it is the product of more than one prime numbers.
