What's the Least Common Multiple (LCM) of 9 and 57?

Answer

LCM of 9 and 57 is 171

(One hundred seventy-one)

Finding LCM for 9 and 57 using GCF of these numbers

The first method to find LCM for numbers 9 and 57 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 9 and 57 is 3, so

LCM = (9 × 57) ÷ 3

LCM = 513 ÷ 3

LCM = 171

Finding LCM for 9 and 57 by Listing Multiples

The second method to find LCM for numbers 9 and 57 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180, 189

Multiples of 57: 57, 114, 171, 228, 285

So the LCM for 9 and 57 is 171

Finding LCM for 9 and 57 by Prime Factorization

Another method to find LCM for numbers 9 and 57 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 9: 3, 3 (exponent form: 32)

All Prime Factors of 57: 3, 19 (exponent form: 31, 191)

32 × 191 = 171
