Answer
(Six hundred sixty-seven)
Finding LCM for 23 and 29 using GCF of these numbers
The first method to find LCM for numbers 23 and 29 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 23 and 29 is 1, so
LCM = (23 × 29) ÷ 1
LCM = 667 ÷ 1
LCM = 667
Finding LCM for 23 and 29 by Listing Multiples
The second method to find LCM for numbers 23 and 29 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 23: 23, 46, 69, 92, 115, 138, 161, 184, 207, 230, 253, 276, 299, 322, 345, 368, 391, 414, 437, 460, 483, 506, 529, 552, 575, 598, 621, 644, 667, 690, 713
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, 725
So the LCM for 23 and 29 is 667
Finding LCM for 23 and 29 by Prime Factorization
Another method to find LCM for numbers 23 and 29 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 23: 23 (exponent form: 231)
All Prime Factors of 29: 29 (exponent form: 291)
231 × 291 = 667
