HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 966, 820 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 966, 820 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 966, 820 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 966, 820 is 2.

HCF(966, 820) = 2

Highest common factor (HCF) of 966, 820 is 2.

Highest Common Factor of 966,820 using Euclid's algorithm

Highest Common Factor of 966,820 is 2

Step 1: Since 966 > 820, we apply the division lemma to 966 and 820, to get

966 = 820 x 1 + 146

Step 2: Since the reminder 820 ≠ 0, we apply division lemma to 146 and 820, to get

820 = 146 x 5 + 90

Step 3: We consider the new divisor 146 and the new remainder 90, and apply the division lemma to get

146 = 90 x 1 + 56

We consider the new divisor 90 and the new remainder 56,and apply the division lemma to get

90 = 56 x 1 + 34

We consider the new divisor 56 and the new remainder 34,and apply the division lemma to get

56 = 34 x 1 + 22

We consider the new divisor 34 and the new remainder 22,and apply the division lemma to get

34 = 22 x 1 + 12

We consider the new divisor 22 and the new remainder 12,and apply the division lemma to get

22 = 12 x 1 + 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 966 and 820 is 2

Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(22,12) = HCF(34,22) = HCF(56,34) = HCF(90,56) = HCF(146,90) = HCF(820,146) = HCF(966,820) .
