The prime factorization of 15 is 3 x 5. There are four fifteens there, so the prime factorization is 34 x 54
The prime factorization of 20 is, 2 squared times 5( because two is prime' 2 times 2 is 4, times 5(which is prime) equals 20)
2 x 2 x 2 x 3 = 24 2 x 2 x 2 x 5 = 40
The prime factorization is... 2x2x2x2x2x5x5
Prime factorization.
The prime factorization of 21 is: 3 x 7

Only integers have prime numbers but as a decimal 27/125 = 0.216

21 x 2 does not equal 40. 21 is not a prime number.
2 x 2 x 2 x 3 = 24 2 x 2 x 2 x 5 = 40
