LCM for 22 and 29
What's the Least Common Multiple (LCM) of 22 and 29?
Answer
(Six hundred thirty-eight)
Finding LCM for 22 and 29 using GCF of these numbers
The first method to find LCM for numbers 22 and 29 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 22 and 29 is 1, so
LCM = (22 × 29) ÷ 1
LCM = 638 ÷ 1
LCM = 638
Finding LCM for 22 and 29 by Listing Multiples
The second method to find LCM for numbers 22 and 29 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, 396, 418, 440, 462, 484, 506, 528, 550, 572, 594, 616, 638, 660, 682
Multiples of 29: 29, 58, 87, 116, 145, 174, 203, 232, 261, 290, 319, 348, 377, 406, 435, 464, 493, 522, 551, 580, 609, 638, 667, 696
So the LCM for 22 and 29 is 638
Finding LCM for 22 and 29 by Prime Factorization
Another method to find LCM for numbers 22 and 29 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 29: 29 (exponent form: 291)
21 × 111 × 291 = 638
