What's the Least Common Multiple (LCM) of 5 and 43?

Answer

LCM of 5 and 43 is
215

(Two hundred fifteen)

Finding LCM for 5 and 43 using GCF of these numbers

The first method to find LCM for numbers 5 and 43 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 5 and 43 is 1, so

LCM = (5 × 43) ÷ 1

LCM = 215 ÷ 1

LCM = 215

Finding LCM for 5 and 43 by Listing Multiples

The second method to find LCM for numbers 5 and 43 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140, 145, 150, 155, 160, 165, 170, 175, 180, 185, 190, 195, 200, 205, 210, 215, 220, 225

Multiples of 43: 43, 86, 129, 172, 215, 258, 301

So the LCM for 5 and 43 is 215

Finding LCM for 5 and 43 by Prime Factorization

Another method to find LCM for numbers 5 and 43 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 5: 5 (exponent form: 51)

All Prime Factors of 43: 43 (exponent form: 431)

51 × 431 = 215
