Composite number :- Having factor more than one. ( except 1 and the number itself )
( 5 × 7 × 13 + 7 )
= 7 ( 65 + 1 )
= 7 ( 66 )
= 7 × 2 × 3 × 11
Since the number have more than one factor that's Y it is a composite number.
( 5 × 7 × 13 + 7 )
= 7 ( 65 + 1 )
= 7 ( 66 )
= 7 × 2 × 3 × 11
Since the number have more than one factor that's Y it is a composite number.
