What's the Least Common Multiple (LCM) of 1 and 56?

Answer

LCM of 1 and 56 is
56

(Fifty-six)

Finding LCM for 1 and 56 using GCF of these numbers

The first method to find LCM for numbers 1 and 56 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 1 and 56 is 1, so

LCM = (1 × 56) ÷ 1

LCM = 56 ÷ 1

LCM = 56

Finding LCM for 1 and 56 by Listing Multiples

The second method to find LCM for numbers 1 and 56 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, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58

Multiples of 56: 56, 112, 168

So the LCM for 1 and 56 is 56

Finding LCM for 1 and 56 by Prime Factorization

Another method to find LCM for numbers 1 and 56 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 56: 2, 2, 2, 7 (exponent form: 23, 71)

LCM = 56
