HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 781, 6481, 2392 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 781, 6481, 2392 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 781, 6481, 2392 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 781, 6481, 2392 is 1.

HCF(781, 6481, 2392) = 1

Highest common factor (HCF) of 781, 6481, 2392 is 1.

Highest Common Factor of 781,6481,2392 using Euclid's algorithm

Highest Common Factor of 781,6481,2392 is 1

Step 1: Since 6481 > 781, we apply the division lemma to 6481 and 781, to get

6481 = 781 x 8 + 233

Step 2: Since the reminder 781 ≠ 0, we apply division lemma to 233 and 781, to get

781 = 233 x 3 + 82

Step 3: We consider the new divisor 233 and the new remainder 82, and apply the division lemma to get

233 = 82 x 2 + 69

We consider the new divisor 82 and the new remainder 69,and apply the division lemma to get

82 = 69 x 1 + 13

We consider the new divisor 69 and the new remainder 13,and apply the division lemma to get

69 = 13 x 5 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 781 and 6481 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(69,13) = HCF(82,69) = HCF(233,82) = HCF(781,233) = HCF(6481,781) .

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

Step 1: Since 2392 > 1, we apply the division lemma to 2392 and 1, to get

2392 = 1 x 2392 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 2392 is 1

Notice that 1 = HCF(2392,1) .
