HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 856, 561, 767 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 856, 561, 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 856, 561, 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 856, 561, 767 is 1.

HCF(856, 561, 767) = 1

HCF of 856, 561, 767 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 856, 561, 767 is 1.

Highest Common Factor of 856,561,767 using Euclid's algorithm

Highest Common Factor of 856,561,767 is 1

Step 1: Since 856 > 561, we apply the division lemma to 856 and 561, to get

856 = 561 x 1 + 295

Step 2: Since the reminder 561 ≠ 0, we apply division lemma to 295 and 561, to get

561 = 295 x 1 + 266

Step 3: We consider the new divisor 295 and the new remainder 266, and apply the division lemma to get

295 = 266 x 1 + 29

We consider the new divisor 266 and the new remainder 29,and apply the division lemma to get

266 = 29 x 9 + 5

We consider the new divisor 29 and the new remainder 5,and apply the division lemma to get

29 = 5 x 5 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 856 and 561 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(29,5) = HCF(266,29) = HCF(295,266) = HCF(561,295) = HCF(856,561) .

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) .
