What's the Least Common Multiple (LCM) of 75 and 105?

Answer

LCM of 75 and 105 is 525

(Five hundred twenty-five)

Finding LCM for 75 and 105 using GCF of these numbers

The first method to find LCM for numbers 75 and 105 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 75 and 105 is 15, so

LCM = (75 × 105) ÷ 15

LCM = 7875 ÷ 15

LCM = 525

Finding LCM for 75 and 105 by Listing Multiples

The second method to find LCM for numbers 75 and 105 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 75: 75, 150, 225, 300, 375, 450, 525, 600, 675

Multiples of 105: 105, 210, 315, 420, 525, 630, 735

So the LCM for 75 and 105 is 525

Finding LCM for 75 and 105 by Prime Factorization

Another method to find LCM for numbers 75 and 105 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

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

All Prime Factors of 105: 3, 5, 7 (exponent form: 31, 51, 71)

31 × 52 × 71 = 525
