Question

find the LCM of 16,17,18.

Answer 1

We need to find the lcm
Or
Lcm can be also called as Least Common Factor.

We will solve this by the process of prime Factorization.

The numbers are 16, 17, 18.

So
Let's do the prime Factorization of these numbers :-

$16 = 2 \times 2 \times 2 \times 2 \\ \\ 17 = 1 \times 17 \\ \\ 18 = 2 \times 3 \times 3$
Now,

Let's find the common terms in all the rows.

Common number is 1

In first two rows is 1
And
Last to rows is 1

First and last row is 2

Now,
Let's multiply this by remaining numbers

So,

The lcm is

2*2*2*2*17 *3 *3
Which is equal 2448

Hence,

The lcm is equal to 2448.

Answer 2

16 = 2×2×2×2
17 = 17 × 1
18 = 2× 3× 3

LCM of 16,17,18 = 2^4 × 17 × 3^2 = 2,448

this is your answer......☺☺☺☺
