If you mean using numbers 2, 3 and 7 then one solution is :-
32 x 7 = 9 x 7 = 63
19 + 21 + 23 = 63
Among the numbers 23, 33, 43, and 63, only 33 and 63 are composite. A composite number has more than two distinct positive divisors, while prime numbers have exactly two. Both 23 and 43 are prime, while 33 (divisible by 1, 3, 11, and 33) and 63 (divisible by 1, 3, 7, 9, 21, and 63) have additional divisors.
