HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 920, 191, 212 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 920, 191, 212 is 1 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 920, 191, 212 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 920, 191, 212 is 1.

HCF(920, 191, 212) = 1

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

HCF of:

Highest common factor (HCF) of 920, 191, 212 is 1.

Highest Common Factor of 920,191,212 using Euclid's algorithm

Highest Common Factor of 920,191,212 is 1

Step 1: Since 920 > 191, we apply the division lemma to 920 and 191, to get

920 = 191 x 4 + 156

Step 2: Since the reminder 191 ≠ 0, we apply division lemma to 156 and 191, to get

191 = 156 x 1 + 35

Step 3: We consider the new divisor 156 and the new remainder 35, and apply the division lemma to get

156 = 35 x 4 + 16

We consider the new divisor 35 and the new remainder 16,and apply the division lemma to get

35 = 16 x 2 + 3

We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get

16 = 3 x 5 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 920 and 191 is 1

Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(35,16) = HCF(156,35) = HCF(191,156) = HCF(920,191) .

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

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

212 = 1 x 212 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 212 is 1

Notice that 1 = HCF(212,1) .
