HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 961 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 671, 961 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 671, 961 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 671, 961 is 1.

HCF(671, 961) = 1

HCF of 671, 961 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 671, 961 is 1.

Highest Common Factor of 671,961 using Euclid's algorithm

Highest Common Factor of 671,961 is 1

Step 1: Since 961 > 671, we apply the division lemma to 961 and 671, to get

961 = 671 x 1 + 290

Step 2: Since the reminder 671 ≠ 0, we apply division lemma to 290 and 671, to get

671 = 290 x 2 + 91

Step 3: We consider the new divisor 290 and the new remainder 91, and apply the division lemma to get

290 = 91 x 3 + 17

We consider the new divisor 91 and the new remainder 17,and apply the division lemma to get

91 = 17 x 5 + 6

We consider the new divisor 17 and the new remainder 6,and apply the division lemma to get

17 = 6 x 2 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 671 and 961 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(17,6) = HCF(91,17) = HCF(290,91) = HCF(671,290) = HCF(961,671) .
