What is the least common multiple of 55 and 15?

Answer 1

lol i have this on a math assigment so when i find it I'll tell u! its uh.........oh 165
There are several ways of finding the LCM.

1) Express each number in terms of its prime factors.

15 =3 x 5

55 = 5 x 11

The LCM is the product of the highest power of each prime factor

The highest power of each factor is 31, 51 and 111.

The LCM is therefore 3 x 5 x 11 = 165.

2) As both numbers have 5 as a factor, take the product of both numbers and divide by their common factor of 5 : 15 x 55 ÷ 5 = 165.
