HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 66, 76, 624 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 66, 76, 624 is 2 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 66, 76, 624 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 66, 76, 624 is 2.

HCF(66, 76, 624) = 2

HCF of 66, 76, 624 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 66, 76, 624 is 2.

Highest Common Factor of 66,76,624 using Euclid's algorithm

Highest Common Factor of 66,76,624 is 2

Step 1: Since 76 > 66, we apply the division lemma to 76 and 66, to get

76 = 66 x 1 + 10

Step 2: Since the reminder 66 ≠ 0, we apply division lemma to 10 and 66, to get

66 = 10 x 6 + 6

Step 3: We consider the new divisor 10 and the new remainder 6, and apply the division lemma to get

10 = 6 x 1 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 66 and 76 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(66,10) = HCF(76,66) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 624 > 2, we apply the division lemma to 624 and 2, to get

624 = 2 x 312 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 624 is 2

Notice that 2 = HCF(624,2) .
