HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 212, 66 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 212, 66 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 212, 66 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 212, 66 is 2.

HCF(212, 66) = 2

HCF of 212, 66 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 212, 66 is 2.

Highest Common Factor of 212,66 using Euclid's algorithm

Highest Common Factor of 212,66 is 2

Step 1: Since 212 > 66, we apply the division lemma to 212 and 66, to get

212 = 66 x 3 + 14

Step 2: Since the reminder 66 ≠ 0, we apply division lemma to 14 and 66, to get

66 = 14 x 4 + 10

Step 3: We consider the new divisor 14 and the new remainder 10, and apply the division lemma to get

14 = 10 x 1 + 4

We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get

10 = 4 x 2 + 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 212 and 66 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(66,14) = HCF(212,66) .
