What's the Least Common Multiple (LCM) of 22 and 30?

Answer

LCM of 22 and 30 is 330

(Three hundred thirty)

Finding LCM for 22 and 30 using GCF of these numbers

The first method to find LCM for numbers 22 and 30 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 22 and 30 is 2, so

LCM = (22 × 30) ÷ 2

LCM = 660 ÷ 2

LCM = 330

Finding LCM for 22 and 30 by Listing Multiples

The second method to find LCM for numbers 22 and 30 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 22: 22, 44, 66, 88, 110, 132, 154, 176, 198, 220, 242, 264, 286, 308, 330, 352, 374

Multiples of 30: 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, 390

So the LCM for 22 and 30 is 330

Finding LCM for 22 and 30 by Prime Factorization

Another method to find LCM for numbers 22 and 30 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 22: 2, 11 (exponent form: 21, 111)

All Prime Factors of 30: 2, 3, 5 (exponent form: 21, 31, 51)

21 × 111 × 31 × 51 = 330
