LCM for 8 and 100
What's the Least Common Multiple (LCM) of 8 and 100?
(Two hundred)
Finding LCM for 8 and 100 using GCF's of these numbers
The first method to find LCM for numbers 8 and 100 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 8 and 100 is 4, so
LCM = (8 × 100) ÷ 4
LCM = 800 ÷ 4
LCM = 200
Finding LCM for 8 and 100 by Listing Multiples
The second method to find LCM for numbers 8 and 100 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, 128, 136, 144, 152, 160, 168, 176, 184, 192, 200, 208, 216
Multiples of 100: 100, 200, 300, 400
So the LCM for 8 and 100 is 200
Finding LCM for 8 and 100 by Prime Factorization
Another method to find LCM for numbers 8 and 100 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 8: 2, 2, 2 (exponent form: 23)
All Prime Factors of 100: 2, 2, 5, 5 (exponent form: 22, 52)
23 × 52 = 200
