Generic way of finding multiples less than a given number.
X / Y = Z
X * 1 to X * the integer part of Z are your positive multiples.
For example:
100 / 21 = 4.76...
4 is the integer part of Z, so your multiples are:
0 * 21 = 0
1 * 21 = 21
2 * 21 = 42
3 * 21 = 63
4 * 21 = 84
Works for any X, Y, and Z :
X = 140, Y=15
140 / 15 = 9
So all the multiples from 1 - 9 are less tahn 140.

Just multiply 21 by integers (i.e. 1, 2, 3...) until the final value goes over 100.
21*1= 21
21*2= 42
21*3= 63
21*4= 84

9 = 3*3, 21=3*7. The common multiple less than 100 is 3*3*7=63. You find this by taking the highest power of each prime number from each number. For the prime factor 3, the highest power is 2, i.e. 3*3; for the prime factor 7, the highest power is 1, i.e. 7. Then multiply the factors together, (3*3)*(7) = 3*3*7 = 63.
