HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 681, 531, 76 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 681, 531, 76 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 681, 531, 76 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 681, 531, 76 is 1.

HCF(681, 531, 76) = 1

Highest Common Factor of 681,531,76 using Euclid's algorithm

Highest Common Factor of 681,531,76 is 1

Step 1: Since 681 > 531, we apply the division lemma to 681 and 531, to get

681 = 531 x 1 + 150

Step 2: Since the reminder 531 ≠ 0, we apply division lemma to 150 and 531, to get

531 = 150 x 3 + 81

Step 3: We consider the new divisor 150 and the new remainder 81, and apply the division lemma to get

150 = 81 x 1 + 69

We consider the new divisor 81 and the new remainder 69,and apply the division lemma to get

81 = 69 x 1 + 12

We consider the new divisor 69 and the new remainder 12,and apply the division lemma to get

69 = 12 x 5 + 9

We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get

12 = 9 x 1 + 3

We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get

9 = 3 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 681 and 531 is 3

Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(69,12) = HCF(81,69) = HCF(150,81) = HCF(531,150) = HCF(681,531) .


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

Step 1: Since 76 > 3, we apply the division lemma to 76 and 3, to get

76 = 3 x 25 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 76 is 1

Notice that 1 = HCF(3,1) = HCF(76,3) .
