Question

how do we find hcf and lcm by division method​

Answer 1

Answer:

First lets take HCF

Lets take three numbers

16, 18, 2

Divide 18÷2

Ans. 9

Divide 16÷9

You first get 7

You can't divide it by nine

So, the hcf of all three numbers is 1

Now lets take lcm

Take 3 numbers

We will again take 2, 16,18

2 (2 16 18)

2 .(1 8 9)

2 .(1 4 9)

2 (1 2 9)

3 (1 1 9)

3 ( 1 1 3)

( 1 1 1)

So the lcm of 2,16&18 is 2*2*2*2*3*3

18*8

136
