LCM for 1 and 17
What's the Least Common Multiple (LCM) of 1 and 17?
(Seventeen)
Finding LCM for 1 and 17 using GCF's of these numbers
The first method to find LCM for numbers 1 and 17 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 1 and 17 is 1, so
LCM = (1 × 17) ÷ 1
LCM = 17 ÷ 1
LCM = 17
Finding LCM for 1 and 17 by Listing Multiples
The second method to find LCM for numbers 1 and 17 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, 13, 14, 15, 16, 17, 18, 19
Multiples of 17: 17, 34, 51, 68, 85, 102, 119, 136, 153, 170, 187, 204, 221, 238, 255, 272, 289, 306, 323, [...], 17
So the LCM for 1 and 17 is 17
Finding LCM for 1 and 17 by Prime Factorization
Another method to find LCM for numbers 1 and 17 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 17: 17 (exponent form: 171)
11 × 171 = 17
