HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 311, 996, 780 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 311, 996, 780 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 311, 996, 780 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 311, 996, 780 is 1.

HCF(311, 996, 780) = 1

Highest common factor (HCF) of 311, 996, 780 is 1.

Highest Common Factor of 311,996,780 using Euclid's algorithm

Highest Common Factor of 311,996,780 is 1

Step 1: Since 996 > 311, we apply the division lemma to 996 and 311, to get

996 = 311 x 3 + 63

Step 2: Since the reminder 311 ≠ 0, we apply division lemma to 63 and 311, to get

311 = 63 x 4 + 59

Step 3: We consider the new divisor 63 and the new remainder 59, and apply the division lemma to get

63 = 59 x 1 + 4

We consider the new divisor 59 and the new remainder 4,and apply the division lemma to get

59 = 4 x 14 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 311 and 996 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(59,4) = HCF(63,59) = HCF(311,63) = HCF(996,311) .

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

Step 1: Since 780 > 1, we apply the division lemma to 780 and 1, to get

780 = 1 x 780 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 780 is 1

Notice that 1 = HCF(780,1) .
