HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 518, 681, 936 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 518, 681, 936 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 518, 681, 936 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 518, 681, 936 is 1.

HCF(518, 681, 936) = 1

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

HCF of:

Highest common factor (HCF) of 518, 681, 936 is 1.

Highest Common Factor of 518,681,936 using Euclid's algorithm

Highest Common Factor of 518,681,936 is 1

Step 1: Since 681 > 518, we apply the division lemma to 681 and 518, to get

681 = 518 x 1 + 163

Step 2: Since the reminder 518 ≠ 0, we apply division lemma to 163 and 518, to get

518 = 163 x 3 + 29

Step 3: We consider the new divisor 163 and the new remainder 29, and apply the division lemma to get

163 = 29 x 5 + 18

We consider the new divisor 29 and the new remainder 18,and apply the division lemma to get

29 = 18 x 1 + 11

We consider the new divisor 18 and the new remainder 11,and apply the division lemma to get

18 = 11 x 1 + 7

We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get

11 = 7 x 1 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 518 and 681 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(18,11) = HCF(29,18) = HCF(163,29) = HCF(518,163) = HCF(681,518) .


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

Step 1: Since 936 > 1, we apply the division lemma to 936 and 1, to get

936 = 1 x 936 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 936 is 1

Notice that 1 = HCF(936,1) .
