Answer 1

(17×11×2)+(17×11×5)
1309
divide it by 1,2,3,4,5,6,7,8,9
n it is divisible by 7 so it's a composite number

Answer 2

(17×11×2)+(17×11×5)
17×11×(2+5)
17×11×7 = 1309

A composite number is mulptiple of more than 2 number i.e 1 and number itself

here the number is muptiple of 1309, 1 , 17 , 11 and 7 so it is a composite number
