Finding LCM for 4 and 10 using GCF's of these numbers

The first method to find LCM for numbers 4 and 10 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 4 and 10 is 2, so

LCM = (4 × 10) ÷ 2

LCM = 40 ÷ 2

LCM = 20

Finding LCM for 4 and 10 by Listing Multiples

The second method to find LCM for numbers 4 and 10 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 4: 4, 8, 12, 16, 20, 24, 28

Multiples of 10: 10, 20, 30, 40

So the LCM for 4 and 10 is 20

Finding LCM for 4 and 10 by Prime Factorization

Another method to find LCM for numbers 4 and 10 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 4: 2, 2 (exponent form: 22)

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

22 × 51 = 20
