for numbers that are prime and have no common
factor, their product is the LCM..
so,
LCM = 5 x 11 = 55

To determine the least common multiple of any two (or more) numbers, you need to break the number down into its factors.
11 = 1x11
5 = 1x5
Then you multiply the factors together, and only counting 'common' ones once.
Therefore the least common multiple for 11 and 5 would be:
LCM = 1 x 11 x 5 = 55
... Take two other number as an example: 6 and 4
6 = 3x2
4 = 2x2
LCM = 3 x 2 x 2 = 12

It means which multiple of 5 (count by fives: 5, 10, 15, 20...) is the same as which multiple of 11 (count by elevens: 11, 22, 33, 44 ...) The first one to match is 55, the least common multiple. Answer: C.

5 and 11 are both prime numbers, therefore the least common multiple can only be 5*11=55

the least common multiple of 5 & 11 is the diect multiple of the two number provided they are prime factors. so in this cae the L. C.M will be 5*11=55.

Anytime you have 2 prime numbers just multiply them for the
least common multiple.
