HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 961, 692, 808 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 961, 692, 808 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 961, 692, 808 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 961, 692, 808 is 1.

HCF(961, 692, 808) = 1

HCF of 961, 692, 808 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 961, 692, 808 is 1.

Highest Common Factor of 961,692,808 using Euclid's algorithm

Highest Common Factor of 961,692,808 is 1

Step 1: Since 961 > 692, we apply the division lemma to 961 and 692, to get

961 = 692 x 1 + 269

Step 2: Since the reminder 692 ≠ 0, we apply division lemma to 269 and 692, to get

692 = 269 x 2 + 154

Step 3: We consider the new divisor 269 and the new remainder 154, and apply the division lemma to get

269 = 154 x 1 + 115

We consider the new divisor 154 and the new remainder 115,and apply the division lemma to get

154 = 115 x 1 + 39

We consider the new divisor 115 and the new remainder 39,and apply the division lemma to get

115 = 39 x 2 + 37

We consider the new divisor 39 and the new remainder 37,and apply the division lemma to get

39 = 37 x 1 + 2

We consider the new divisor 37 and the new remainder 2,and apply the division lemma to get

37 = 2 x 18 + 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 961 and 692 is 1

Notice that 1 = HCF(2,1) = HCF(37,2) = HCF(39,37) = HCF(115,39) = HCF(154,115) = HCF(269,154) = HCF(692,269) = HCF(961,692) .

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

Step 1: Since 808 > 1, we apply the division lemma to 808 and 1, to get

808 = 1 x 808 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 808 is 1

Notice that 1 = HCF(808,1) .
