Yes!
Another opinion:
No, you could not, because there is no such thing.
Whatever number you bring me, and tell me that it is the greatest common
multiple of two numbers, then no matter how big your number is, all I have to
do is multiply your number by the product of those two numbers, and I have a
new, bigger, common multiple.
No. Numbers don't stop.
No, because the number of common multiples of any two nonzero numbers is infinite.
Three numbers that have a greatest common factor of 25 are any multiples of 25 such as 25, 50, and 75. The greatest common factor of these numbers is 25 because it is the largest number that divides each of them evenly. Another set of numbers could be 125, 150, and 175, as they are also multiples of 25 with a greatest common factor of 25.
20 and 30 could be two such numbers.
13, 26, 39 are three numbers with a GCF of 13.
it can be 60,10
The smallest of the two numbers could be 850.
Multiples of 6 are 6, 12, 18, 24, 30, 36... Multiples of 10 are 10, 20, 30, 40... The LCM of 6 and 10 is 30. The greatest common multiple could go into infinity.
I suppose the greatest common multiple could be considered as infinity. Once you calculate the least common multiple, you could keep doubling it forever. You could never determine a greatest common multiple, because every time you decided on a number, you could double it or multiply it by another positive integer, and have an even larger common multiple. There are an infinite number of common multiples.
Those two numbers could be 18 and 36.
The numbers could be 850 and 1700. There are other possibilities.
5 and 10 is one possibility.
