What's the Least Common Multiple (LCM) of 65 and 75?

Answer

LCM of 65 and 75 is
975

(Nine hundred seventy-five)

Finding LCM for 65 and 75 using GCF of these numbers

The first method to find LCM for numbers 65 and 75 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 65 and 75 is 5, so

LCM = (65 × 75) ÷ 5

LCM = 4,875 ÷ 5

LCM = 975

Finding LCM for 65 and 75 by Listing Multiples

The second method to find LCM for numbers 65 and 75 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 65: 65, 130, 195, 260, 325, 390, 455, 520, 585, 650, 715, 780, 845, 910, 975, 1,040, 1,105

Multiples of 75: 75, 150, 225, 300, 375, 450, 525, 600, 675, 750, 825, 900, 975, 1,050, 1,125

So the LCM for 65 and 75 is 975

Finding LCM for 65 and 75 by Prime Factorization

Another method to find LCM for numbers 65 and 75 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 65: 5, 13 (exponent form: 51, 131)

All Prime Factors of 75: 3, 5, 5 (exponent form: 31, 52)

52 × 131 × 31 = 975
