Answer: LCM of 40 and 75 is 600

(Six hundred)

Finding LCM for 40 and 75 using GCF's of these numbers

The first method to find LCM for numbers 40 and 75 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 40 and 75 is 5, so

LCM = (40 × 75) ÷ 5

LCM = 3000 ÷ 5

LCM = 600

Finding LCM for 40 and 75 by Listing Multiples

The second method to find LCM for numbers 40 and 75 is to list out the common multiples for both nubmers and pick the first which matching:

Multiples of 40: 40, 80, 120, 160, 200, 240, 280, 320, 360, 400, 440, 480, 520, 560, 600, 640, 680

Multiples of 75: 75, 150, 225, 300, 375, 450, 525, 600, 675, 750

So the LCM for 40 and 75 is 600

Finding LCM for 40 and 75 by Prime Factorization

Another method to find LCM for numbers 40 and 75 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 40: 2, 2, 2, 5 (exponent form: 23, 51)

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

23 × 52 × 31 = 600
