LCM for 10 and 27
What's the Least Common Multiple (LCM) of 10 and 27?
(Two hundred seventy)
Finding LCM for 10 and 27 using GCF's of these numbers
The first method to find LCM for numbers 10 and 27 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 10 and 27 is 1, so
LCM = (10 × 27) ÷ 1
LCM = 270 ÷ 1
LCM = 270
Finding LCM for 10 and 27 by Listing Multiples
The second method to find LCM for numbers 10 and 27 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290
Multiples of 27: 27, 54, 81, 108, 135, 162, 189, 216, 243, 270, 297, 324
So the LCM for 10 and 27 is 270
Finding LCM for 10 and 27 by Prime Factorization
Another method to find LCM for numbers 10 and 27 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 10: 2, 5 (exponent form: 21, 51)
All Prime Factors of 27: 3, 3, 3 (exponent form: 33)
21 × 51 × 33 = 270
