HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 682, 143, 965 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 682, 143, 965 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 682, 143, 965 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 682, 143, 965 is 1.

HCF(682, 143, 965) = 1

HCF of 682, 143, 965 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 682, 143, 965 is 1.

Highest Common Factor of 682,143,965 using Euclid's algorithm

Highest Common Factor of 682,143,965 is 1

Step 1: Since 682 > 143, we apply the division lemma to 682 and 143, to get

682 = 143 x 4 + 110

Step 2: Since the reminder 143 ≠ 0, we apply division lemma to 110 and 143, to get

143 = 110 x 1 + 33

Step 3: We consider the new divisor 110 and the new remainder 33, and apply the division lemma to get

110 = 33 x 3 + 11

We consider the new divisor 33 and the new remainder 11, and apply the division lemma to get

33 = 11 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 682 and 143 is 11

Notice that 11 = HCF(33,11) = HCF(110,33) = HCF(143,110) = HCF(682,143) .


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

Step 1: Since 965 > 11, we apply the division lemma to 965 and 11, to get

965 = 11 x 87 + 8

Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 8 and 11, to get

11 = 8 x 1 + 3

Step 3: We consider the new divisor 8 and the new remainder 3, and apply the division lemma to get

8 = 3 x 2 + 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 11 and 965 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(965,11) .
