HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 68, 979, 193 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 68, 979, 193 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 68, 979, 193 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 68, 979, 193 is 1.

HCF(68, 979, 193) = 1

HCF of 68, 979, 193 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 68, 979, 193 is 1.

Highest Common Factor of 68,979,193 using Euclid's algorithm

Highest Common Factor of 68,979,193 is 1

Step 1: Since 979 > 68, we apply the division lemma to 979 and 68, to get

979 = 68 x 14 + 27

Step 2: Since the reminder 68 ≠ 0, we apply division lemma to 27 and 68, to get

68 = 27 x 2 + 14

Step 3: We consider the new divisor 27 and the new remainder 14, and apply the division lemma to get

27 = 14 x 1 + 13

We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get

14 = 13 x 1 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 68 and 979 is 1

Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(27,14) = HCF(68,27) = HCF(979,68) .

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

Step 1: Since 193 > 1, we apply the division lemma to 193 and 1, to get

193 = 1 x 193 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 193 is 1

Notice that 1 = HCF(193,1) .
