What's the Least Common Multiple (LCM) of 19 and 22?

Answer

LCM of 19 and 22 is 418

(Four hundred eighteen)

Finding LCM for 19 and 22 using GCF of these numbers

The first method to find LCM for numbers 19 and 22 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 19 and 22 is 1, so

LCM = (19 × 22) ÷ 1

LCM = 418 ÷ 1

LCM = 418

Finding LCM for 19 and 22 by Listing Multiples

The second method to find LCM for numbers 19 and 22 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 19: 19, 38, 57, 76, 95, 114, 133, 152, 171, 190, 209, 228, 247, 266, 285, 304, 323, 342, 361, 380, 399, 418, 437, 456

Multiples of 22: 22, 44, 66, 88, 110, 132, 154, 176, 198, 220, 242, 264, 286, 308, 330, 352, 374, 396, 418, 440, 462

So the LCM for 19 and 22 is 418

Finding LCM for 19 and 22 by Prime Factorization

Another method to find LCM for numbers 19 and 22 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 19: 19 (exponent form: 191)

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

191 × 21 × 111 = 418
