What's the Least Common Multiple (LCM) of 12 and 100?

Answer

LCM of 12 and 100 is
300

(Three hundred)

Finding LCM for 12 and 100 using GCF of these numbers

The first method to find LCM for numbers 12 and 100 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 12 and 100 is 4, so

LCM = (12 × 100) ÷ 4

LCM = 1,200 ÷ 4

LCM = 300

Finding LCM for 12 and 100 by Listing Multiples

The second method to find LCM for numbers 12 and 100 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216, 228, 240, 252, 264, 276, 288, 300, 312, 324

Multiples of 100: 100, 200, 300, 400, 500

So the LCM for 12 and 100 is 300

Finding LCM for 12 and 100 by Prime Factorization

Another method to find LCM for numbers 12 and 100 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 12: 2, 2, 3 (exponent form: 22, 31)

All Prime Factors of 100: 2, 2, 5, 5 (exponent form: 22, 52)

22 × 31 × 52 = 300
