Answer: LCM of 21 and 26 is 546

(Five hundred forty-six)

Finding LCM for 21 and 26 using GCF's of these numbers

The first method to find LCM for numbers 21 and 26 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 21 and 26 is 1, so

LCM = (21 × 26) ÷ 1

LCM = 546 ÷ 1

LCM = 546

Finding LCM for 21 and 26 by Listing Multiples

The second method to find LCM for numbers 21 and 26 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 21: 21, 42, 63, 84, 105, 126, 147, 168, 189, 210, 231, 252, 273, 294, 315, 336, 357, 378, 399, 420, 441, 462, 483, 504, 525, 546, 567, 588

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

So the LCM for 21 and 26 is 546

Finding LCM for 21 and 26 by Prime Factorization

Another method to find LCM for numbers 21 and 26 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 21: 3, 7 (exponent form: 31, 71)

All Prime Factors of 26: 2, 13 (exponent form: 21, 131)

31 × 71 × 21 × 131 = 546
