Finding LCM for 30 and 100 using GCF's of these numbers
The first method to find LCM for numbers 30 and 100 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 30 and 100 is 10, so
LCM = (30 × 100) ÷ 10
LCM = 3000 ÷ 10
LCM = 300
Finding LCM for 30 and 100 by Listing Multiples
The second method to find LCM for numbers 30 and 100 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, 270, 300, 330, 360
Multiples of 100: 100, 200, 300, 400, 500
So the LCM for 30 and 100 is 300
Finding LCM for 30 and 100 by Prime Factorization
Another method to find LCM for numbers 30 and 100 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 100: 2, 2, 5, 5 (exponent form: 22, 52)
22 × 31 × 52 = 300
