HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 832, 638, 765 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 832, 638, 765 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 832, 638, 765 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 832, 638, 765 is 1.

HCF(832, 638, 765) = 1

Highest common factor (HCF) of 832, 638, 765 is 1.

Highest Common Factor of 832,638,765 using Euclid's algorithm

Highest Common Factor of 832,638,765 is 1

Step 1: Since 832 > 638, we apply the division lemma to 832 and 638, to get

832 = 638 x 1 + 194

Step 2: Since the reminder 638 ≠ 0, we apply division lemma to 194 and 638, to get

638 = 194 x 3 + 56

Step 3: We consider the new divisor 194 and the new remainder 56, and apply the division lemma to get

194 = 56 x 3 + 26

We consider the new divisor 56 and the new remainder 26,and apply the division lemma to get

56 = 26 x 2 + 4

We consider the new divisor 26 and the new remainder 4,and apply the division lemma to get

26 = 4 x 6 + 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 832 and 638 is 2

Notice that 2 = HCF(4,2) = HCF(26,4) = HCF(56,26) = HCF(194,56) = HCF(638,194) = HCF(832,638) .

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

Step 1: Since 765 > 2, we apply the division lemma to 765 and 2, to get

765 = 2 x 382 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 765 is 1

Notice that 1 = HCF(2,1) = HCF(765,2) .
