What's the Least Common Multiple (LCM) of 9 and 25?

Answer

LCM of 9 and 25 is 225

(Two hundred twenty-five)

Finding LCM for 9 and 25 using GCF of these numbers

The first method to find LCM for numbers 9 and 25 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 9 and 25 is 1, so

LCM = (9 × 25) ÷ 1

LCM = 225 ÷ 1

LCM = 225

Finding LCM for 9 and 25 by Listing Multiples

The second method to find LCM for numbers 9 and 25 is to list out the common multiples for both numbers and pick the first one that matches:

Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180, 189, 198, 207, 216, 225, 234, 243

Multiples of 25: 25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275

So the LCM for 9 and 25 is 225

Finding LCM for 9 and 25 by Prime Factorization

Another method to find LCM for numbers 9 and 25 is to list all Prime Factors for both numbers and multiply the highest exponent prime factors:

All Prime Factors of 9: 3, 3 (exponent form: 32)

All Prime Factors of 25: 5, 5 (exponent form: 52)

32 × 52 = 225
