Answer:

[tex](2)(3^2)(5^2)[/tex]

Step-by-step explanation:

we know that

The Least Common Multiple (LCM) of a group of numbers is the smallest number that is a multiple of all the numbers.

we have

15,18 and 25

Decompose the numbers in prime factors

[tex]15=(3)(5)[/tex]

[tex]18=(2)(3^2)[/tex]

[tex]25=(5^2)[/tex]

Multiply common and uncommon numbers with their greatest exponent

so

The LCM is equal to

[tex]LCM=(2)(3^2)(5^2)[/tex]

[tex]LCM=450[/tex]
