Answer

LCM of 18 and 36 is 36

(Thirty-six)

Finding LCM for 18 and 36 using GCF of these numbers

The first method to find LCM for numbers 18 and 36 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 18 and 36 is 18, so

LCM = (18 × 36) ÷ 18

LCM = 648 ÷ 18

LCM = 36

Finding LCM for 18 and 36 by Listing Multiples

The second method to find LCM for numbers 18 and 36 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 18: 18, 36, 54, 72

Multiples of 36: 36, 72, 108

So the LCM for 18 and 36 is 36

Finding LCM for 18 and 36 by Prime Factorization

Another method to find LCM for numbers 18 and 36 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 18: 2, 3, 3 (exponent form: 21, 32)

All Prime Factors of 36: 2, 2, 3, 3 (exponent form: 22, 32)

22 × 32 = 36
