LCM for 13 and 35
What's the Least Common Multiple (LCM) of 13 and 35?
(Four hundred fifty-five)
Finding LCM for 13 and 35 using GCF's of these numbers
The first method to find LCM for numbers 13 and 35 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 13 and 35 is 1, so
LCM = (13 × 35) ÷ 1
LCM = 455 ÷ 1
LCM = 455
Finding LCM for 13 and 35 by Listing Multiples
The second method to find LCM for numbers 13 and 35 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, 338, 351, 364, 377, 390, 403, 416, 429, 442, 455, 468, 481
Multiples of 35: 35, 70, 105, 140, 175, 210, 245, 280, 315, 350, 385, 420, 455, 490, 525
So the LCM for 13 and 35 is 455
Finding LCM for 13 and 35 by Prime Factorization
Another method to find LCM for numbers 13 and 35 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 35: 5, 7 (exponent form: 51, 71)
131 × 51 × 71 = 455
