Question

explain why 11 into 13 into 15 into 17 + 17 is a composite number

Answer 1

11 * 13 * 15 * 17 + 17 is a composite number because we can take 17 out as common

17 ( 11 * 13 * 17 * 1 +1)

composite number means numbers that have factors other than 1 and itself also hence they have 17 as a factor, which is other than 1 or itself

thereby it is a composite number
