A single number can't have a common factor. In case you meant the product of its prime fators, that's 2^-4 x 5^-4.
OK suppose this is your questionwhat is the least common multiple of 21 and 16?21 is 3 times 716 is 2 to the 4th power (2 times 2 times 2 times 2)So these numbers have no factors in common.Therefore, to find the least common multiple, you multiply them together:21 x 16 = 126 + 210 = 336 hope this helps give more detail you only put 21 whats the other number?

324 has only one prime factor: 2
2 x 5 x a x a x a x a
(x - 3)(x + 3)(x2 + 9)
4(64 - 125b) or -4(125b - 64)
(w - 2)(w + 2)(w^2 + 4)
The greatest threat was from Athens in the 5th Century BCE, then Thebes and then Macedonia in the 4th Century BCE.
(x^2 - 2x + 2)(x^2 + 2x + 2)
24 or two to the fourth power or 2 to the 4th or 2 to the 4th power they are all the same, just worded differently.
