LCM for 1 and 16
What's the Least Common Multiple (LCM) of 1 and 16?
Answer
(Sixteen)
Finding LCM for 1 and 16 using GCF of these numbers
The first method to find LCM for numbers 1 and 16 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:
LCM = (Number1 × Number2) ÷ GCF
GCF of numbers 1 and 16 is 1, so
LCM = (1 × 16) ÷ 1
LCM = 16 ÷ 1
LCM = 16
Finding LCM for 1 and 16 by Listing Multiples
The second method to find LCM for numbers 1 and 16 is to list out the common multiples for both numbers and pick the first one that matches:
Multiples of 1: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18
Multiples of 16: 16, 32, 48
So the LCM for 1 and 16 is 16
Finding LCM for 1 and 16 by Prime Factorization
Another method to find LCM for numbers 1 and 16 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:
1 has no prime factors — 1 is neither prime nor composite
All Prime Factors of 16: 2, 2, 2, 2 (exponent form: 24)
LCM = 16
