HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 657, 556, 769 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 657, 556, 769 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 657, 556, 769 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 657, 556, 769 is 1.

HCF(657, 556, 769) = 1

HCF of 657, 556, 769 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 657, 556, 769 is 1.

Highest Common Factor of 657,556,769 using Euclid's algorithm

Highest Common Factor of 657,556,769 is 1

Step 1: Since 657 > 556, we apply the division lemma to 657 and 556, to get

657 = 556 x 1 + 101

Step 2: Since the reminder 556 ≠ 0, we apply division lemma to 101 and 556, to get

556 = 101 x 5 + 51

Step 3: We consider the new divisor 101 and the new remainder 51, and apply the division lemma to get

101 = 51 x 1 + 50

We consider the new divisor 51 and the new remainder 50,and apply the division lemma to get

51 = 50 x 1 + 1

We consider the new divisor 50 and the new remainder 1,and apply the division lemma to get

50 = 1 x 50 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 657 and 556 is 1

Notice that 1 = HCF(50,1) = HCF(51,50) = HCF(101,51) = HCF(556,101) = HCF(657,556) .


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

Step 1: Since 769 > 1, we apply the division lemma to 769 and 1, to get

769 = 1 x 769 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 769 is 1

Notice that 1 = HCF(769,1) .
