What's the Least Common Multiple (LCM) of 33 and 55?

Answer

LCM of 33 and 55 is 165

(One hundred sixty-five)

Finding LCM for 33 and 55 using GCF of these numbers

The first method to find LCM for numbers 33 and 55 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 33 and 55 is 11, so

LCM = (33 × 55) ÷ 11

LCM = 1815 ÷ 11

LCM = 165

Finding LCM for 33 and 55 by Listing Multiples

The second method to find LCM for numbers 33 and 55 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 33: 33, 66, 99, 132, 165, 198, 231

Multiples of 55: 55, 110, 165, 220, 275

So the LCM for 33 and 55 is 165

Finding LCM for 33 and 55 by Prime Factorization

Another method to find LCM for numbers 33 and 55 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 33: 3, 11 (exponent form: 31, 111)

All Prime Factors of 55: 5, 11 (exponent form: 51, 111)

31 × 111 × 51 = 165
