Step-by-step explanation:

Given numbers are 10,15 and 45

To find,

The LCM of the given numbers

Solution:

Recall the concept:

LCM of two or more numbers is defined as the smallest number which can be divided by the given numbers.

Here the given numbers are 10,15 and 45

The prime factorization of 10 = 2×5

The prime factorization of 15 = 3×5

The prime factorization of 45 = 3×3×5

The smallest number which can be divided by 2×5,3×5,3×3×5

= 2×3×3×5

= 90

The smallest number which can be divided by 10,15 and 45 = 90
