How to find the HCF of 1.2 and 0.12?
The HCF of the two numbers 1.2 and 0.12 is the largest possible number which divides both the numbers completely.
Answer: The HCF of 1.2 and 0.12 is 0.12
The procedure is simple. We will convert the given decimals into like decimals in which the number of digits after the decimal point are the same.
Hence, 1.2 will become 1.20, while 0.12 will remain 0.12
Now, in order to remove the decimal, we will multiply both the numbers by 100. This will make it 1.20 × 100 = 120; and 0.12 × 100 = 12
So, now our numbers are 120 and 12.
Now, we will 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
Thus, the HCF of 1.2 and 0.12 is 0.12
