Answer:
Love this proof. Still remember by heart.
Step-by-step explanation:
1 X 2 x 3 x 4 x 5 x 6 x 7 + 5
= 5 ( 1 X 2 x 3 x 4 x 6 x 7 + 1)
= 5 ( 1008 + 1 )
= 5 x 1009
Therefore, 1 X 2 x 3 x 4 x 5 x 6 x 7 + 5 can be expressed as a product of numbers other than 1 and itself. Thus, it is a composite number.
Hence, proved.
Hope it helped!
