LCM for 11 and 33
What's the Least Common Multiple (LCM) of 11 and 33?
(Thirty-three)
Finding LCM for 11 and 33 using GCF's of these numbers
The first method to find LCM for numbers 11 and 33 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 11 and 33 is 11, so
LCM = (11 × 33) ÷ 11
LCM = 363 ÷ 11
LCM = 33
Finding LCM for 11 and 33 by Listing Multiples
The second method to find LCM for numbers 11 and 33 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 11: 11, 22, 33, 44, 55
Multiples of 33: 33, 66, 99, 132, 165, [...], 33
So the LCM for 11 and 33 is 33
Finding LCM for 11 and 33 by Prime Factorization
Another method to find LCM for numbers 11 and 33 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 11: 11 (exponent form: 111)
All Prime Factors of 33: 3, 11 (exponent form: 31, 111)
111 × 31 = 33
