HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 617, 870, 767 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 617, 870, 767 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 617, 870, 767 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 617, 870, 767 is 1.

HCF(617, 870, 767) = 1

Highest common factor (HCF) of 617, 870, 767 is 1.

Highest Common Factor of 617,870,767 using Euclid's algorithm

Highest Common Factor of 617,870,767 is 1

Step 1: Since 870 > 617, we apply the division lemma to 870 and 617, to get

870 = 617 x 1 + 253

Step 2: Since the reminder 617 ≠ 0, we apply division lemma to 253 and 617, to get

617 = 253 x 2 + 111

Step 3: We consider the new divisor 253 and the new remainder 111, and apply the division lemma to get

253 = 111 x 2 + 31

We consider the new divisor 111 and the new remainder 31,and apply the division lemma to get

111 = 31 x 3 + 18

We consider the new divisor 31 and the new remainder 18,and apply the division lemma to get

31 = 18 x 1 + 13

We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get

18 = 13 x 1 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 617 and 870 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(31,18) = HCF(111,31) = HCF(253,111) = HCF(617,253) = HCF(870,617) .

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

Step 1: Since 767 > 1, we apply the division lemma to 767 and 1, to get

767 = 1 x 767 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 767 is 1

Notice that 1 = HCF(767,1) .
