Answer

LCM of 10 and 8 is 40

(Forty)

Finding LCM for 10 and 8 using GCF of these numbers

The first method to find LCM for numbers 10 and 8 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 10 and 8 is 2, so

LCM = (10 × 8) ÷ 2

LCM = 80 ÷ 2

LCM = 40

Finding LCM for 10 and 8 by Listing Multiples

The second method to find LCM for numbers 10 and 8 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 10: 10, 20, 30, 40, 50, 60

Multiples of 8: 8, 16, 24, 32, 40, 48, 56

So the LCM for 10 and 8 is 40

Finding LCM for 10 and 8 by Prime Factorization

Another method to find LCM for numbers 10 and 8 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 10: 2, 5 (exponent form: 21, 51)

All Prime Factors of 8: 2, 2, 2 (exponent form: 23)

23 × 51 = 40
