HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 824, 637, 862 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 824, 637, 862 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 824, 637, 862 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 824, 637, 862 is 1.

HCF(824, 637, 862) = 1

Highest common factor (HCF) of 824, 637, 862 is 1.

Highest Common Factor of 824,637,862 using Euclid's algorithm

Highest Common Factor of 824,637,862 is 1

Step 1: Since 824 > 637, we apply the division lemma to 824 and 637, to get

824 = 637 x 1 + 187

Step 2: Since the reminder 637 ≠ 0, we apply division lemma to 187 and 637, to get

637 = 187 x 3 + 76

Step 3: We consider the new divisor 187 and the new remainder 76, and apply the division lemma to get

187 = 76 x 2 + 35

We consider the new divisor 76 and the new remainder 35,and apply the division lemma to get

76 = 35 x 2 + 6

We consider the new divisor 35 and the new remainder 6,and apply the division lemma to get

35 = 6 x 5 + 5

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 824 and 637 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(35,6) = HCF(76,35) = HCF(187,76) = HCF(637,187) = HCF(824,637) .

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

Step 1: Since 862 > 1, we apply the division lemma to 862 and 1, to get

862 = 1 x 862 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 862 is 1

Notice that 1 = HCF(862,1) .
