The GCF of 16, 63 and 75 is 1.The factors for each number are: 16 - 1, 2, 4, 8, 16 63 - 1, 3, 7, 9, 21, 63 75 - 1, 3, 5, 15, 25, 75 The only number in common is the 1, so this makes it the greatest common factor.The factors of 63 are: 1, 3, 7, 9, 21, 63The factors of 75 are: 1, 3, 5, 15, 25, 75The common factors are: 1, 3The Greatest Common Factor (GCF) is: 3The GCF is 1.

The answer is 25,200.

75 = 3*5*5, so the first pair that comes to mind is 3*5 and 5*5.LCM(15, 25) = 75.And it conveniently happens to be that GCD*(15, 25) = 5.So {15, 25} is the answer (at least an answer).*GCD is "Greatest Common Divisor" and a more official way of saying GCF.* * * * *Yes, it is an answer.Consider LCM/GCF = 75/5 = 15If p and q are any two coprime factors of LCM/GCF = 15, then p*GCF and q*GCF will be an answer.The above answer used p = 3 and q = 5.The other possible pair is p = 1 and q = 15 which gives the pair as 5 and 75.
