**Least common multiple (LCM)**

The *least common multiple* (LCM) of 2 numbers is the smallest
number that they both divide evenly into.
One good way to find the least common multiple of 2 numbers is to multiply
both numbers by 1,2,3,4,5... and then find the first multiple that appears in both lists.

For example, find the least common multiple of 6 and 8:

Multiples of 6: 6 12 18 24 30 36 42 48 54 60
Multiples of 8: 8 16 24 32 40 48 56 64 72 80

The first number that appears in both lists is 24. (48 appears also,
but it is not 'least'), so 24 is the LCM of 6 and 8.

Now, can you find the *least common multiple* of 10 and 35?
