or

24,36

or

36,48

24-12=12

hcf of 12 and 24 is 12

36-24=12

hcf of 36 and 24=12

36-48=12

hcf of 36 and 48 is 12

Let

**a**and

**b**are two numbers and

**HCF = 12**then

**a = 12 * x, x > 0**

**b = 12 * y, y > 0**

Also

**a - b = 12,**this gives

**x = y + 1**

So, finally

**a = 12 * (y + 1)**and

**b = 12 * y, y > 0**

So numbers will be

**(24, 12) or (12, 24)**

**(36, 24) or (24, 36)**

(48, 36) or (48, 36)

(60, 48) or (48, 60)

and so on..

(48, 36) or (48, 36)

(60, 48) or (48, 60)

and so on..
