What's the Least Common Multiple (LCM) of 5 and 75?

Answer

LCM of 5 and 75 is
75

(Seventy-five)

Finding LCM for 5 and 75 using GCF of these numbers

The first method to find LCM for numbers 5 and 75 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 5 and 75 is 5, so

LCM = (5 × 75) ÷ 5

LCM = 375 ÷ 5

LCM = 75

Finding LCM for 5 and 75 by Listing Multiples

The second method to find LCM for numbers 5 and 75 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

Multiples of 75: 75, 150, 225

So the LCM for 5 and 75 is 75

Finding LCM for 5 and 75 by Prime Factorization

Another method to find LCM for numbers 5 and 75 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 75: 3, 5, 5 (exponent form: 31, 52)

52 × 31 = 75
