What is the least common multiple of 11 and 9?

Answer 1

The LCM of 9 and 11 is 99.

The least common multiple is the smallest positive number that is the multiple of two or more numbers.

9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99

11: 11, 22, 33, 44, 55, 66, 77, 88, 99

The LCM of 9 and 11 is 99.

Answer 2

99

The least common multiple can be found by writing up a bunch of multiples of each number, and finding where they meet. See below:

9-18,27,36,45,54,63,72,81,91,99

11-22,33,44,55,66,77,88,99

We see that these meet at 99, so this is our least common multiple

Answer 3

The multiples of 9 are 9, 18, 27, 36. 45, 54, 63, 72, 81, 90, 99, 108…The multiples of 11 are 11, 22, 33, 44, 55, 66, 77. 88, 99, 110…

The LCM of 9 and 11 is 99.

Answer 4

The word "least" is a superlative: that means there can be only one answer. There is only one least common multiple, not more than one common multiples.

LCM(9, 11) = 99.

Answer 5

The LCM of 9 and 11 is 99.
