90, 180, 270, ...

Answer:

45 ,90

Step-by-step explanation:

We are given that LCM of 12 and  number  N is 180.

In order to find the number we will find the factors of 180 and 12

[tex]180=2\times 2\times 3\times 3\times 5[/tex]

[tex]12=2\times 2\times 3[/tex]

[tex]45=3\times 3\times 5[/tex]

[tex]90=2\times 3\times 3\times 5[/tex]

LCM(12,45)=[tex]2\times 2\times 3\times 3\times 5=180[/tex]

LCM(12,90)=[tex]2\times 2\times 3\times 3\times 5=180[/tex]

LCM of 12 and 45 is 180

LCM of 12 and 90 is 180.

Hence, possible of  N is 45 and 90.
