LCM for 19 and 24
What's the Least Common Multiple (LCM) of 19 and 24?
(Four hundred fifty-six)
Finding LCM for 19 and 24 using GCF's of these numbers
The first method to find LCM for numbers 19 and 24 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 19 and 24 is 1, so
LCM = (19 × 24) ÷ 1
LCM = 456 ÷ 1
LCM = 456
Finding LCM for 19 and 24 by Listing Multiples
The second method to find LCM for numbers 19 and 24 is to list out the common multiples for both nubmers and pick the first which matching:
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, 475, 494
Multiples of 24: 24, 48, 72, 96, 120, 144, 168, 192, 216, 240, 264, 288, 312, 336, 360, 384, 408, 432, 456, 480, 504
So the LCM for 19 and 24 is 456
Finding LCM for 19 and 24 by Prime Factorization
Another method to find LCM for numbers 19 and 24 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 24: 2, 2, 2, 3 (exponent form: 23, 31)
191 × 23 × 31 = 456
