What's the Least Common Multiple (LCM) of 51 and 85?

Answer: LCM of 51 and 85 is 255

(Two hundred fifty-five)

Finding LCM for 51 and 85 using GCF's of these numbers

The first method to find LCM for numbers 51 and 85 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 51 and 85 is 17, so

LCM = (51 × 85) ÷ 17

LCM = 4335 ÷ 17

LCM = 255

Finding LCM for 51 and 85 by Listing Multiples

The second method to find LCM for numbers 51 and 85 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 51: 51, 102, 153, 204, 255, 306, 357

Multiples of 85: 85, 170, 255, 340, 425

So the LCM for 51 and 85 is 255

Finding LCM for 51 and 85 by Prime Factorization

Another method to find LCM for numbers 51 and 85 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 51: 3, 17 (exponent form: 3¹, 17¹)

All Prime Factors of 85: 5, 17 (exponent form: 5¹, 17¹)

3¹ × 17¹ × 5¹ = 255
