(One hundred fifty)
Finding LCM for 30 and 50 using GCF's of these numbers
The first method to find LCM for numbers 30 and 50 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 30 and 50 is 10, so
LCM = (30 × 50) ÷ 10
LCM = 1500 ÷ 10
LCM = 150
Finding LCM for 30 and 50 by Listing Multiples
The second method to find LCM for numbers 30 and 50 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
Multiples of 50: 50, 100, 150, 200, 250
So the LCM for 30 and 50 is 150
Finding LCM for 30 and 50 by Prime Factorization
Another method to find LCM for numbers 30 and 50 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 50: 2, 5, 5 (exponent form: 21, 52)
21 × 31 × 52 = 150
