LCM for 35 and 56
What's the Least Common Multiple (LCM) of 35 and 56?
(Two hundred eighty)
Finding LCM for 35 and 56 using GCF's of these numbers
The first method to find LCM for numbers 35 and 56 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 35 and 56 is 7, so
LCM = (35 × 56) ÷ 7
LCM = 1960 ÷ 7
LCM = 280
Finding LCM for 35 and 56 by Listing Multiples
The second method to find LCM for numbers 35 and 56 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
Multiples of 56: 56, 112, 168, 224, 280, 336, 392
So the LCM for 35 and 56 is 280
Finding LCM for 35 and 56 by Prime Factorization
Another method to find LCM for numbers 35 and 56 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 56: 2, 2, 2, 7 (exponent form: 23, 71)
51 × 71 × 23 = 280
