LCM for 2 and 10

What's the Least Common Multiple (LCM) of 2 and 10?

Answer: LCM of 2 and 10 is 10

(Ten)

Finding LCM for 2 and 10 using GCF's of these numbers

The first method to find LCM for numbers 2 and 10 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 2 and 10 is 2, so

LCM = (2 × 10) ÷ 2

LCM = 20 ÷ 2

LCM = 10

Finding LCM for 2 and 10 by Listing Multiples

The second method to find LCM for numbers 2 and 10 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 2: 2, 4, 6, 8, 10, 12, 14

Multiples of 10: 10, 20, 30, 40, 50, 60, 70, [...], 10

So the LCM for 2 and 10 is 10

Finding LCM for 2 and 10 by Prime Factorization

Another method to find LCM for numbers 2 and 10 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 2: 2 (exponent form: 21)

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

21 × 51 = 10
