HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 865, 8579, 7492 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 865, 8579, 7492 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 865, 8579, 7492 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 865, 8579, 7492 is 1.

HCF(865, 8579, 7492) = 1

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

HCF of:

Highest common factor (HCF) of 865, 8579, 7492 is 1.

Highest Common Factor of 865,8579,7492 using Euclid's algorithm

Highest Common Factor of 865,8579,7492 is 1

Step 1: Since 8579 > 865, we apply the division lemma to 8579 and 865, to get

8579 = 865 x 9 + 794

Step 2: Since the reminder 865 ≠ 0, we apply division lemma to 794 and 865, to get

865 = 794 x 1 + 71

Step 3: We consider the new divisor 794 and the new remainder 71, and apply the division lemma to get

794 = 71 x 11 + 13

We consider the new divisor 71 and the new remainder 13,and apply the division lemma to get

71 = 13 x 5 + 6

We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get

13 = 6 x 2 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 865 and 8579 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(71,13) = HCF(794,71) = HCF(865,794) = HCF(8579,865) .

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

Step 1: Since 7492 > 1, we apply the division lemma to 7492 and 1, to get

7492 = 1 x 7492 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 7492 is 1

Notice that 1 = HCF(7492,1) .
