Finding LCM for 13 and 23 using GCF's of these numbers
The first method to find LCM for numbers 13 and 23 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 13 and 23 is 1, so
LCM = (13 × 23) ÷ 1
LCM = 299 ÷ 1
LCM = 299
Finding LCM for 13 and 23 by Listing Multiples
The second method to find LCM for numbers 13 and 23 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 13: 13, 26, 39, 52, 65, 78, 91, 104, 117, 130, 143, 156, 169, 182, 195, 208, 221, 234, 247, 260, 273, 286, 299, 312, 325
Multiples of 23: 23, 46, 69, 92, 115, 138, 161, 184, 207, 230, 253, 276, 299, 322, 345
So the LCM for 13 and 23 is 299
Finding LCM for 13 and 23 by Prime Factorization
Another method to find LCM for numbers 13 and 23 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 13: 13 (exponent form: 131)
All Prime Factors of 23: 23 (exponent form: 231)
131 × 231 = 299
