LCM for 51 and 54
What's the Least Common Multiple (LCM) of 51 and 54?
Answer
(Nine hundred eighteen)
Finding LCM for 51 and 54 using GCF of these numbers
The first method to find LCM for numbers 51 and 54 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 51 and 54 is 3, so
LCM = (51 × 54) ÷ 3
LCM = 2754 ÷ 3
LCM = 918
Finding LCM for 51 and 54 by Listing Multiples
The second method to find LCM for numbers 51 and 54 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 51: 51, 102, 153, 204, 255, 306, 357, 408, 459, 510, 561, 612, 663, 714, 765, 816, 867, 918, 969, 1020
Multiples of 54: 54, 108, 162, 216, 270, 324, 378, 432, 486, 540, 594, 648, 702, 756, 810, 864, 918, 972, 1026
So the LCM for 51 and 54 is 918
Finding LCM for 51 and 54 by Prime Factorization
Another method to find LCM for numbers 51 and 54 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 51: 3, 17 (exponent form: 31, 171)
All Prime Factors of 54: 2, 3, 3, 3 (exponent form: 21, 33)
33 × 171 × 21 = 918
