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.

5 and 75 15 and 25

25 and 75, among others, have an LCM of 75.

15 and 25

5 and 75 have a GCF of 5 and an LCM of 75.

Lcm: 150 gcf: 15

150 is LCM and GCF is 15

The GCF is 5. The LCM is 315.

Since 15 is a factor of 75, it is automatically the GCF. Since 75 is a multiple of 15, it is automatically the LCM.

3 and 675, respectively.

The LCM of 30 and 75 is 150. Their GCF is 15.

The LCM is 25200 The GCF is 1.
