LCM for 1 and 10
What's the Least Common Multiple (LCM) of 1 and 10?
(Ten)
Finding LCM for 1 and 10 using GCF's of these numbers
The first method to find LCM for numbers 1 and 10 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 1 and 10 is 1, so
LCM = (1 × 10) ÷ 1
LCM = 10 ÷ 1
LCM = 10
Finding LCM for 1 and 10 by Listing Multiples
The second method to find LCM for numbers 1 and 10 is to list out the common multiples for both nubmers and pick the first which matching:
Multiples of 1: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
Multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, [...], 10
So the LCM for 1 and 10 is 10
Finding LCM for 1 and 10 by Prime Factorization
Another method to find LCM for numbers 1 and 10 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
All Prime Factors of 1: 1 (exponent form: 11)
All Prime Factors of 10: 2, 5 (exponent form: 21, 51)
11 × 21 × 51 = 10
