HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 861, 610, 530 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 861, 610, 530 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 861, 610, 530 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 861, 610, 530 is 1.

HCF(861, 610, 530) = 1

Highest common factor (HCF) of 861, 610, 530 is 1.

Highest Common Factor of 861,610,530 using Euclid's algorithm

Highest Common Factor of 861,610,530 is 1

Step 1: Since 861 > 610, we apply the division lemma to 861 and 610, to get

861 = 610 x 1 + 251

Step 2: Since the reminder 610 ≠ 0, we apply division lemma to 251 and 610, to get

610 = 251 x 2 + 108

Step 3: We consider the new divisor 251 and the new remainder 108, and apply the division lemma to get

251 = 108 x 2 + 35

We consider the new divisor 108 and the new remainder 35,and apply the division lemma to get

108 = 35 x 3 + 3

We consider the new divisor 35 and the new remainder 3,and apply the division lemma to get

35 = 3 x 11 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 861 and 610 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(35,3) = HCF(108,35) = HCF(251,108) = HCF(610,251) = HCF(861,610) .

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

Step 1: Since 530 > 1, we apply the division lemma to 530 and 1, to get

530 = 1 x 530 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 530 is 1

Notice that 1 = HCF(530,1) .
