LCM for 30 and 36
What's the Least Common Multiple (LCM) of 30 and 36?
(One hundred eighty)
Finding LCM for 30 and 36 using GCF's of these numbers
The first method to find LCM for numbers 30 and 36 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 30 and 36 is 6, so
LCM = (30 × 36) ÷ 6
LCM = 1080 ÷ 6
LCM = 180
Finding LCM for 30 and 36 by Listing Multiples
The second method to find LCM for numbers 30 and 36 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 30: 30, 60, 90, 120, 150, 180, 210, 240
Multiples of 36: 36, 72, 108, 144, 180, 216, 252
So the LCM for 30 and 36 is 180
Finding LCM for 30 and 36 by Prime Factorization
Another method to find LCM for numbers 30 and 36 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 30: 2, 3, 5 (exponent form: 21, 31, 51)
All Prime Factors of 36: 2, 2, 3, 3 (exponent form: 22, 32)
22 × 32 × 51 = 180
