HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 866, 798 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 866, 798 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 866, 798 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 866, 798 is 2.

HCF(866, 798) = 2

Highest common factor (HCF) of 866, 798 is 2.

Highest Common Factor of 866,798 using Euclid's algorithm

Highest Common Factor of 866,798 is 2

Step 1: Since 866 > 798, we apply the division lemma to 866 and 798, to get

866 = 798 x 1 + 68

Step 2: Since the reminder 798 ≠ 0, we apply division lemma to 68 and 798, to get

798 = 68 x 11 + 50

Step 3: We consider the new divisor 68 and the new remainder 50, and apply the division lemma to get

68 = 50 x 1 + 18

We consider the new divisor 50 and the new remainder 18,and apply the division lemma to get

50 = 18 x 2 + 14

We consider the new divisor 18 and the new remainder 14,and apply the division lemma to get

18 = 14 x 1 + 4

We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get

14 = 4 x 3 + 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 866 and 798 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(18,14) = HCF(50,18) = HCF(68,50) = HCF(798,68) = HCF(866,798) .
