What is the least common multiple of 2 5 and 9?

Answer 1

That would be 90.
you may think it might be 90,

90
90 which is 2 x 5 x 9

No smaller number can be divided evenly by each of the three numbers.

Answer 2

The least common multiple (LCM) of 2, 5, and 9 is the smallest multiple that all three numbers share. To find the LCM, you can first find the prime factorization of each number: 2 = 2, 5 = 5, and 9 = 3 x 3. Then, identify the highest power of each prime factor that appears in any of the numbers: 2 x 3 x 3 x 5 = 90. Therefore, the LCM of 2, 5, and 9 is 90.

Answer 3

2=2 x 1

5=5 x 1

9=3^2

2 x 3^2 x 5= 2 x 9 x 5= 90

The LCM of 2,5,9 is 90.

Answer 4

the LCM of 5,9, and 2 is 90

Answer 5
