Least common multiple of 7 and 9

LEAST common multiple, or LOWEST common multiple??
A multiple of 7 is found by multiplying the 7 with a counting number. So 7 x1=7 - 7 is a multiple. 7x2=14 - 14 is a multiple.
If you find all of the multiples of 7, then all of the multiples of 9 and compare the lists, the lowest one they both have in common is 63. Not sure about how to find the least common multiple though...
(Yes, a much quicker option for finding an LCM, for those experienced with multiples, is to multiply the two given numbers together)

list the multiples of 7 and 9.
however, since they are both prime, just multiply 7 and 9.
LCM: 63
...i think...

That's usually found by multiplying your numbers together.
In this case, 63.
