What's the Least Common Multiple (LCM) of 10 and 45?

Answer

LCM of 10 and 45 is 90

(Ninety)

Finding LCM for 10 and 45 using GCF of these numbers

The first method to find LCM for numbers 10 and 45 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 10 and 45 is 5, so

LCM = (10 × 45) ÷ 5

LCM = 450 ÷ 5

LCM = 90

Finding LCM for 10 and 45 by Listing Multiples

The second method to find LCM for numbers 10 and 45 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, 70, 80, 90, 100, 110

Multiples of 45: 45, 90, 135, 180

So the LCM for 10 and 45 is 90

Finding LCM for 10 and 45 by Prime Factorization

Another method to find LCM for numbers 10 and 45 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 45: 3, 3, 5 (exponent form: 32, 51)

21 × 51 × 32 = 90
