Find the GCM for 5, 15, 13, 25?

We don't have the GCM and we just have the GCF (greatest common factor) or the LCM (least common multiple).

..5 = .....5
15 = 3 * 5
13 = ...............13
25 = .....5 * 5
---------------------------------
GCF:
....= 1

LCM:
....= 3 * 5 * 5 * 13
....= 975

The greatest common multiple is infinity, for any set of integers which contains a number greater than 1.

If you meant least common multiple, then it is 975.

You can find the GCF or LCM, but to my knowledge there is not a GCM.

LCM- 5: 5, 10, 15, 20, 25, 30, . . .
15: 15, 30, 45, 60 . . .
13: 13, 26, 39, 42, 55, 68, 81, 94, 107 . . .
25: 25, 50, 75, 100, 125, 150, 175 . . .

Eventually you get to that the LCM is 975.
For the GCF, there is no finite GCF for these numbers because they get infinitely larger

Sorry I couldn't help more.

GCM - is greatest common multiple
GCM is infinity
u should ask
Greatest common factor
or Least common multiple
OK

GCM is the greatest common multiple
So, a no. common in 5,15,13,25 is
975

3x5x13=195
