HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 172, 7804, 3966 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 172, 7804, 3966 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 172, 7804, 3966 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 172, 7804, 3966 is 2.

HCF(172, 7804, 3966) = 2

HCF of 172, 7804, 3966 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 172, 7804, 3966 is 2.

Highest Common Factor of 172,7804,3966 using Euclid's algorithm

Highest Common Factor of 172,7804,3966 is 2

Step 1: Since 7804 > 172, we apply the division lemma to 7804 and 172, to get

7804 = 172 x 45 + 64

Step 2: Since the reminder 172 ≠ 0, we apply division lemma to 64 and 172, to get

172 = 64 x 2 + 44

Step 3: We consider the new divisor 64 and the new remainder 44, and apply the division lemma to get

64 = 44 x 1 + 20

We consider the new divisor 44 and the new remainder 20,and apply the division lemma to get

44 = 20 x 2 + 4

We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get

20 = 4 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 172 and 7804 is 4

Notice that 4 = HCF(20,4) = HCF(44,20) = HCF(64,44) = HCF(172,64) = HCF(7804,172) .


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

Step 1: Since 3966 > 4, we apply the division lemma to 3966 and 4, to get

3966 = 4 x 991 + 2

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, 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 4 and 3966 is 2

Notice that 2 = HCF(4,2) = HCF(3966,4) .
