LCM for 26 and 31
What's the Least Common Multiple (LCM) of 26 and 31?
Answer
(Eight hundred six)
Finding LCM for 26 and 31 using GCF of these numbers
The first method to find LCM for numbers 26 and 31 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 26 and 31 is 1, so
LCM = (26 × 31) ÷ 1
LCM = 806 ÷ 1
LCM = 806
Finding LCM for 26 and 31 by Listing Multiples
The second method to find LCM for numbers 26 and 31 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 26: 26, 52, 78, 104, 130, 156, 182, 208, 234, 260, 286, 312, 338, 364, 390, 416, 442, 468, 494, 520, 546, 572, 598, 624, 650, 676, 702, 728, 754, 780, 806, 832, 858
Multiples of 31: 31, 62, 93, 124, 155, 186, 217, 248, 279, 310, 341, 372, 403, 434, 465, 496, 527, 558, 589, 620, 651, 682, 713, 744, 775, 806, 837, 868
So the LCM for 26 and 31 is 806
Finding LCM for 26 and 31 by Prime Factorization
Another method to find LCM for numbers 26 and 31 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 26: 2, 13 (exponent form: 21, 131)
All Prime Factors of 31: 31 (exponent form: 311)
21 × 131 × 311 = 806
