Let N=7*11*13+13
or, N=13*(7*11+1)
Thus N has at least three factors, i.e, 1, 13 and N itself.
Let M=7*6*5*4*3*2*1+5
or, M=5*(7*6*4*3*2*1+1)
Thus M has at least 3 factors, i.e, 1,5 and M itself.
"A composite number is a number which has more than 2 factors."
Hence, by definition, N and M are composite numbers.
Hope this helps.
