This question is asking for the Lowest Common Multiple (LCM) - also called the Least Common Denominator (LCD).
Generally, you can find the LCM of 2 of the numbers, then find the LCM of that number with the third.
Since 3 and 7 are both prime, their LCM is 3x7=21. To find the LCM of 21 and 12, make a list of their multiples until you find a number common to both lists:
12: 12. 24, 36, 48, 60, 72, 84, ...
21: 21, 42, 63, 84, ...
