HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 191, 770, 111 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 191, 770, 111 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 191, 770, 111 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 191, 770, 111 is 1.

HCF(191, 770, 111) = 1

HCF of 191, 770, 111 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 191, 770, 111 is 1.

Highest Common Factor of 191,770,111 using Euclid's algorithm

Highest Common Factor of 191,770,111 is 1

Step 1: Since 770 > 191, we apply the division lemma to 770 and 191, to get

770 = 191 x 4 + 6

Step 2: Since the reminder 191 ≠ 0, we apply division lemma to 6 and 191, to get

191 = 6 x 31 + 5

Step 3: We consider the new divisor 6 and the new remainder 5, and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 191 and 770 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(191,6) = HCF(770,191) .


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

Step 1: Since 111 > 1, we apply the division lemma to 111 and 1, to get

111 = 1 x 111 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 111 is 1

Notice that 1 = HCF(111,1) .
