What's the Least Common Multiple (LCM) of 54 and 56?

Answer

LCM of 54 and 56 is 1,512

(One thousand, five hundred twelve)

Finding LCM for 54 and 56 using GCF of these numbers

The first method to find LCM for numbers 54 and 56 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 54 and 56 is 2, so

LCM = (54 × 56) ÷ 2

LCM = 3024 ÷ 2

LCM = 1512

Finding LCM for 54 and 56 by Listing Multiples

The second method to find LCM for numbers 54 and 56 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 54: 54, 108, 162, 216, 270, 324, 378, 432, 486, 540, 594, 648, 702, 756, 810, 864, 918, 972, 1026, 1080, 1134, 1188, 1242, 1296, 1350, 1404, 1458, 1512, 1566, 1620

Multiples of 56: 56, 112, 168, 224, 280, 336, 392, 448, 504, 560, 616, 672, 728, 784, 840, 896, 952, 1008, 1064, 1120, 1176, 1232, 1288, 1344, 1400, 1456, 1512, 1568, 1624

So the LCM for 54 and 56 is 1512

Finding LCM for 54 and 56 by Prime Factorization

Another method to find LCM for numbers 54 and 56 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 54: 2, 3, 3, 3 (exponent form: 21, 33)

All Prime Factors of 56: 2, 2, 2, 7 (exponent form: 23, 71)

23 × 33 × 71 = 1512
