Finding LCM for 17 and 31 using GCF's of these numbers
The first method to find LCM for numbers 17 and 31 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 17 and 31 is 1, so
LCM = (17 × 31) ÷ 1
LCM = 527 ÷ 1
LCM = 527
Finding LCM for 17 and 31 by Listing Multiples
The second method to find LCM for numbers 17 and 31 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 17: 17, 34, 51, 68, 85, 102, 119, 136, 153, 170, 187, 204, 221, 238, 255, 272, 289, 306, 323, 340, 357, 374, 391, 408, 425, 442, 459, 476, 493, 510, 527, 544, 561
Multiples of 31: 31, 62, 93, 124, 155, 186, 217, 248, 279, 310, 341, 372, 403, 434, 465, 496, 527, 558, 589
So the LCM for 17 and 31 is 527
Finding LCM for 17 and 31 by Prime Factorization
Another method to find LCM for numbers 17 and 31 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 17: 17 (exponent form: 171)
All Prime Factors of 31: 31 (exponent form: 311)
171 × 311 = 527
