Finding LCM for 50 and 70 using GCF's of these numbers
The first method to find LCM for numbers 50 and 70 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 50 and 70 is 10, so
LCM = (50 × 70) ÷ 10
LCM = 3500 ÷ 10
LCM = 350
Finding LCM for 50 and 70 by Listing Multiples
The second method to find LCM for numbers 50 and 70 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 50: 50, 100, 150, 200, 250, 300, 350, 400, 450
Multiples of 70: 70, 140, 210, 280, 350, 420, 490
So the LCM for 50 and 70 is 350
Finding LCM for 50 and 70 by Prime Factorization
Another method to find LCM for numbers 50 and 70 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 50: 2, 5, 5 (exponent form: 21, 52)
All Prime Factors of 70: 2, 5, 7 (exponent form: 21, 51, 71)
21 × 52 × 71 = 350
