What's the Least Common Multiple (LCM) of 48 and 81?

Answer

LCM of 48 and 81 is 1,296

(One thousand, two hundred ninety-six)

Finding LCM for 48 and 81 using GCF of these numbers

The first method to find LCM for numbers 48 and 81 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 48 and 81 is 3, so

LCM = (48 × 81) ÷ 3

LCM = 3888 ÷ 3

LCM = 1296

Finding LCM for 48 and 81 by Listing Multiples

The second method to find LCM for numbers 48 and 81 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 48: 48, 96, 144, 192, 240, 288, 336, 384, 432, 480, 528, 576, 624, 672, 720, 768, 816, 864, 912, 960, 1008, 1056, 1104, 1152, 1200, 1248, 1296, 1344, 1392

Multiples of 81: 81, 162, 243, 324, 405, 486, 567, 648, 729, 810, 891, 972, 1053, 1134, 1215, 1296, 1377, 1458

So the LCM for 48 and 81 is 1296

Finding LCM for 48 and 81 by Prime Factorization

Another method to find LCM for numbers 48 and 81 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 48: 2, 2, 2, 2, 3 (exponent form: 24, 31)

All Prime Factors of 81: 3, 3, 3, 3 (exponent form: 34)

24 × 34 = 1296
