Given : 47 * 19 * 11 + 19 is a composite NUMBER

To Find : Explain why

Solution:

a composite number is a number which have atleast one factor other than number itself and 1.

47 * 19 * 11 + 19

Taking 19 as common

= 19 ( 47 * 11 + 1)

= 19 k

Hence number is FORM 19 * k where 19 and k ≠ 1 and 19k

Hence number has atleast 4 FACTORS , 1 , 19 , k , 19k

where k = 47 * 11 + 1

Hence 47 * 19 * 11 + 19 is a composite number
