HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 787, 806, 877, 64 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 787, 806, 877, 64 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 787, 806, 877, 64 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 787, 806, 877, 64 is 1.

HCF(787, 806, 877, 64) = 1

HCF of 787, 806, 877, 64 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 787, 806, 877, 64 is 1.

Highest Common Factor of 787,806,877,64 using Euclid's algorithm

Highest Common Factor of 787,806,877,64 is 1

Step 1: Since 806 > 787, we apply the division lemma to 806 and 787, to get

806 = 787 x 1 + 19

Step 2: Since the reminder 787 ≠ 0, we apply division lemma to 19 and 787, to get

787 = 19 x 41 + 8

Step 3: We consider the new divisor 19 and the new remainder 8, and apply the division lemma to get

19 = 8 x 2 + 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 787 and 806 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(19,8) = HCF(787,19) = HCF(806,787) .


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

Step 1: Since 877 > 1, we apply the division lemma to 877 and 1, to get

877 = 1 x 877 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 877 is 1

Notice that 1 = HCF(877,1) .


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

Step 1: Since 64 > 1, we apply the division lemma to 64 and 1, to get

64 = 1 x 64 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 64 is 1

Notice that 1 = HCF(64,1) .
