Answer

LCM of 9 and 11 is 99

(Ninety-nine)

Finding LCM for 9 and 11 using GCF of these numbers

The first method to find LCM for numbers 9 and 11 is to find Greatest Common Factor (GCF) of these numbers. Here's the formula:

LCM = (Number1 × Number2) ÷ GCF

GCF of numbers 9 and 11 is 1, so

LCM = (9 × 11) ÷ 1

LCM = 99 ÷ 1

LCM = 99

Finding LCM for 9 and 11 by Listing Multiples

The second method to find LCM for numbers 9 and 11 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

Multiples of 11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121

So the LCM for 9 and 11 is 99

Finding LCM for 9 and 11 by Prime Factorization

Another method to find LCM for numbers 9 and 11 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 11: 11 (exponent form: 111)

32 × 111 = 99
