It is in exponents: 22*3*52*7 = 2100
52 = 2 x 2 x 13 OR 22 x 13
50 = 2 x 5 x 5 OR 2 x 52
1450 as a product of primes = 2 * 5 * 5 * 29
5x5x3
23*32*52 = 1800
20 as a product of primes = 2 * 2 * 5
5*3
YES: 479,011,600 = 24 × 52 × 241 × 4,969
2 * 33 * 72
29 is already prime. Prime numbers can't be products of primes.
25 = 5 x 5 or 52
