HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 364, 770, 781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 364, 770, 781 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 364, 770, 781 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 364, 770, 781 is 1.

HCF(364, 770, 781) = 1

HCF of 364, 770, 781 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 364, 770, 781 is 1.

Highest Common Factor of 364,770,781 using Euclid's algorithm

Highest Common Factor of 364,770,781 is 1

Step 1: Since 770 > 364, we apply the division lemma to 770 and 364, to get

770 = 364 x 2 + 42

Step 2: Since the reminder 364 ≠ 0, we apply division lemma to 42 and 364, to get

364 = 42 x 8 + 28

Step 3: We consider the new divisor 42 and the new remainder 28, and apply the division lemma to get

42 = 28 x 1 + 14

We consider the new divisor 28 and the new remainder 14, and apply the division lemma to get

28 = 14 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 364 and 770 is 14

Notice that 14 = HCF(28,14) = HCF(42,28) = HCF(364,42) = HCF(770,364) .

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

Step 1: Since 781 > 14, we apply the division lemma to 781 and 14, to get

781 = 14 x 55 + 11

Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 11 and 14, to get

14 = 11 x 1 + 3

Step 3: We consider the new divisor 11 and the new remainder 3, and apply the division lemma to get

11 = 3 x 3 + 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 14 and 781 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(14,11) = HCF(781,14) .
