Answer 2

Answer:

195

Step-by-step explanation:

Finding L.C.M.

To find the L.C.M. we find prime factors of the given numbers.

Remember, we consider common prime factors only.

Example: Find the L.C.M. of 12, 16 and 24.

First we find the prime factors of the given numbers

12 = 2 × 2 × 3

16 = 2 × 2 × 2 × 2

24 = 2 × 2 × 2 × 2 × 3

(2 comes maximum 4 times and 3 comes maximum once only.)

L.C.M. = 2 × 2 × 2 × 2 × 3

= 48 which is the product of their prime factors.

You can also find the LCM of two digits when one of them is a prime number by simply multiplying the two digits. Ex - LCM of 13 and 15 we can find by multiplying the two digits.
