The greatest common multiple of any set of integers is infinite.
The greatest common multiple of any set of integers is infinite.--------------------------------------------------------------------------------------------------------Did you perhaps mean:the greatest common FACTOR (the greatest number which divides into 14 and 21 without remainder): gcf(14, 21) = 7;the LOWEST common multiple (the smallest number which is a positive multiple of both 14 and 21): lcm(14, 21) = 42
The greatest common multiple of any set of integers is infinite.
The greatest common multiple of any set of integers is infinite.
The greatest common multiple of any set of integers is infinite.
The greatest common multiple of any set of integers is infinite.
The highest common multiple of 21 and 84 is infinity. The least common multiple, on the other hand, is 84, while the greatest common divisor is 21.
It is infinite but the LCM is 21
