How to find the HCF of 1.2 and 0.12?
HCF of two numbers 1.2 and 0.12 is the largest possible number which divides both the numbers exactly.
Answer: HCF of 1.2 and 0.12 is 0.12
The procedure is simple. We will first try to make both the numbers in the same decimal notations.
Hence, 1.2 will become 1.20, while 0.12 will remain 0.12 only.
Now, in order to remove the decimal, we multiply both of these numbers by 100.
So now our numbers are 120 and 12.
Now we simply try to find the HCF of 120 and 12.
Clearly, the Highest Common Factor (HCF) of 120 and 12 is 12.
But in order to find the answer to our original question, we will have to divide the final answer by 100 (as we had previously multiplied it by 100).
Hence, our required answer will be 12/100 = 0.12
