HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 798, 974, 102 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 798, 974, 102 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 798, 974, 102 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 798, 974, 102 is 2.

HCF(798, 974, 102) = 2

HCF of 798, 974, 102 using Euclid's algorithm

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

Highest common factor (HCF) of 798, 974, 102 is 2.

Highest Common Factor of 798,974,102 using Euclid's algorithm

Highest Common Factor of 798,974,102 is 2

Step 1: Since 974 > 798, we apply the division lemma to 974 and 798, to get

974 = 798 x 1 + 176

Step 2: Since the reminder 798 ≠ 0, we apply division lemma to 176 and 798, to get

798 = 176 x 4 + 94

Step 3: We consider the new divisor 176 and the new remainder 94, and apply the division lemma to get

176 = 94 x 1 + 82

We consider the new divisor 94 and the new remainder 82,and apply the division lemma to get

94 = 82 x 1 + 12

We consider the new divisor 82 and the new remainder 12,and apply the division lemma to get

82 = 12 x 6 + 10

We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get

12 = 10 x 1 + 2

We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get

10 = 2 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 798 and 974 is 2

Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(82,12) = HCF(94,82) = HCF(176,94) = HCF(798,176) = HCF(974,798) .


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

Step 1: Since 102 > 2, we apply the division lemma to 102 and 2, to get

102 = 2 x 51 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 102 is 2

Notice that 2 = HCF(102,2) .
