1, 2, 3, 6, 7, 14, 21, and 42
4 42 in simplest form is 2 21. You have to divide 42 by 2. Whatever you divided the denominator with you have to divide it the same with the numerator. There is your answer. I hope it helps.
21 x 2 = 42
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.
