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

If that's -21 + 14, the answer is -7. If that's -21/14, the answer is -3/2 or -1 and 1/2

(i) There is an infinite number of answers e.g. 7 and 14, 7 and 21, 7 and 28 etc, 14 and 21, 14 and 35, 14 and 49 etc, 21 and 28, 21 and 35, 21 and 49, etc (ii) Several answers: 7 and 10, 10 and 14, 2 and 35, 5 and 14 and so on.

1, 2.

The factors of 21 are 1, 3, 7, and 21.The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36The factors of 14 are 1, 2, 7 and 14.gcf's:21 and 14: 721 and 36: 336 and 14: 236, 14, and 21: 1

Both have four factors. 21 = 7 x 3 and 14 = 7 x 2

The LCM of 14 and 21 is 42. What this means is that 42 is the smallest whole number such that both 14 and 21 divide into it (without remainder). Both 14 and 21 divide into 84, for example, so 84 is a common multiple. But 42 is smaller than 84 so 84 is not the least.
