HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 787, 841, 506 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 787, 841, 506 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, 841, 506 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, 841, 506 is 1.

HCF(787, 841, 506) = 1

HCF of 787, 841, 506 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, 841, 506 is 1.

Highest Common Factor of 787,841,506 using Euclid's algorithm

Highest Common Factor of 787,841,506 is 1

Step 1: Since 841 > 787, we apply the division lemma to 841 and 787, to get

841 = 787 x 1 + 54

Step 2: Since the reminder 787 ≠ 0, we apply division lemma to 54 and 787, to get

787 = 54 x 14 + 31

Step 3: We consider the new divisor 54 and the new remainder 31, and apply the division lemma to get

54 = 31 x 1 + 23

We consider the new divisor 31 and the new remainder 23,and apply the division lemma to get

31 = 23 x 1 + 8

We consider the new divisor 23 and the new remainder 8,and apply the division lemma to get

23 = 8 x 2 + 7

We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get

8 = 7 x 1 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 787 and 841 is 1

Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(23,8) = HCF(31,23) = HCF(54,31) = HCF(787,54) = HCF(841,787) .

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

Step 1: Since 506 > 1, we apply the division lemma to 506 and 1, to get

506 = 1 x 506 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 506 is 1

Notice that 1 = HCF(506,1) .
