HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 787, 216, 796 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 787, 216, 796 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, 216, 796 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, 216, 796 is 1.

HCF(787, 216, 796) = 1

HCF of 787, 216, 796 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 787, 216, 796 is 1.

Highest Common Factor of 787,216,796 using Euclid's algorithm

Highest Common Factor of 787,216,796 is 1

Step 1: Since 787 > 216, we apply the division lemma to 787 and 216, to get

787 = 216 x 3 + 139

Step 2: Since the reminder 216 ≠ 0, we apply division lemma to 139 and 216, to get

216 = 139 x 1 + 77

Step 3: We consider the new divisor 139 and the new remainder 77, and apply the division lemma to get

139 = 77 x 1 + 62

We consider the new divisor 77 and the new remainder 62,and apply the division lemma to get

77 = 62 x 1 + 15

We consider the new divisor 62 and the new remainder 15,and apply the division lemma to get

62 = 15 x 4 + 2

We consider the new divisor 15 and the new remainder 2,and apply the division lemma to get

15 = 2 x 7 + 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 216 is 1

Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(62,15) = HCF(77,62) = HCF(139,77) = HCF(216,139) = HCF(787,216) .

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

Step 1: Since 796 > 1, we apply the division lemma to 796 and 1, to get

796 = 1 x 796 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 796 is 1

Notice that 1 = HCF(796,1) .
