### Detailed Method to Find the HCF of 666,504,63,612 using Euclid's algorithm

Euclid’s algorithm is written as a = bq + r. This is known as the division lemma. The variable r varies according to 0 ≤ r ≤ b. We can use this to figure out the HCF of 666,504,63,612. This is how to do it.

Step 1: The first step is to use the division lemma with 666 and 504 because 666 is greater than 504

666 = 504 x 1 + 162

Step 2: Here, the reminder 504 is not 0, we must use division lemma to 162 and 504, to get

504 = 162 x 3 + 18

Step 3: We consider the new divisor 162 and the new remainder 18, and apply the division lemma to get

162 = 18 x 9 + 0

As you can see, the remainder is zero, so you may end the process at this point. From the last equation, we can determine that the divisor is 18.Therefore, the HCF of 666 and 504 is equal to 18

Notice that 18 = HCF(162,18) = HCF(504,162) = HCF(666,504) .

Now, we must treat the HCF of the first two numbers as the next number in our calculation, and next

Step 1: The first step is to use the division lemma with 63 and 18 because 63 is greater than 18

63 = 18 x 3 + 9

Step 2: Here, the reminder 18 is not 0, we must use division lemma to 9 and 18, to get

18 = 9 x 2 + 0

As you can see, the remainder is zero, so you may end the process at this point. From the last equation, we can determine that the divisor is 9.Therefore, the HCF of 18 and 63 is equal to 9

Notice that 9 = HCF(18,9) = HCF(63,18) .

Now, we must treat the HCF of the first two numbers as the next number in our calculation, and next

Step 1: The first step is to use the division lemma with 612 and 9 because 612 is greater than 9

612 = 9 x 68 + 0

As you can see, the remainder is zero, so you may end the process at this point. From the last equation, we can determine that the divisor is 9.Therefore, the HCF of 9 and 612 is equal to 9

Notice that 9 = HCF(612,9) .

### Result

Hence, the HCF of 666, 504, 63, 612 is equal to 9.
