LCM for 35 and 45
What's the Least Common Multiple (LCM) of 35 and 45?
(Three hundred fifteen)
Finding LCM for 35 and 45 using GCF's of these numbers
The first method to find LCM for numbers 35 and 45 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 35 and 45 is 5, so
LCM = (35 × 45) ÷ 5
LCM = 1575 ÷ 5
LCM = 315
Finding LCM for 35 and 45 by Listing Multiples
The second method to find LCM for numbers 35 and 45 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 35: 35, 70, 105, 140, 175, 210, 245, 280, 315, 350, 385
Multiples of 45: 45, 90, 135, 180, 225, 270, 315, 360, 405
So the LCM for 35 and 45 is 315
Finding LCM for 35 and 45 by Prime Factorization
Another method to find LCM for numbers 35 and 45 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 35: 5, 7 (exponent form: 51, 71)
All Prime Factors of 45: 3, 3, 5 (exponent form: 32, 51)
51 × 71 × 32 = 315
