Answer

LCM of 75 and 180 is
900

(Nine hundred)

Finding LCM for 75 and 180 using GCF of these numbers

The first method to find LCM for numbers 75 and 180 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 75 and 180 is 15, so

LCM = (75 × 180) ÷ 15

LCM = 13500 ÷ 15

LCM = 900

Finding LCM for 75 and 180 by Listing Multiples

The second method to find LCM for numbers 75 and 180 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, 750, 825, 900, 975, 1050

Multiples of 180: 180, 360, 540, 720, 900, 1080, 1260

So the LCM for 75 and 180 is 900

Finding LCM for 75 and 180 by Prime Factorization

Another method to find LCM for numbers 75 and 180 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 180: 2, 2, 3, 3, 5 (exponent form: 22, 32, 51)

32 × 52 × 22 = 900
