HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 210, 383, 781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 210, 383, 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 210, 383, 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 210, 383, 781 is 1.

HCF(210, 383, 781) = 1

Highest common factor (HCF) of 210, 383, 781 is 1.

Highest Common Factor of 210,383,781 using Euclid's algorithm

Highest Common Factor of 210,383,781 is 1

Step 1: Since 383 > 210, we apply the division lemma to 383 and 210, to get

383 = 210 x 1 + 173

Step 2: Since the reminder 210 ≠ 0, we apply division lemma to 173 and 210, to get

210 = 173 x 1 + 37

Step 3: We consider the new divisor 173 and the new remainder 37, and apply the division lemma to get

173 = 37 x 4 + 25

We consider the new divisor 37 and the new remainder 25,and apply the division lemma to get

37 = 25 x 1 + 12

We consider the new divisor 25 and the new remainder 12,and apply the division lemma to get

25 = 12 x 2 + 1

We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 210 and 383 is 1

Notice that 1 = HCF(12,1) = HCF(25,12) = HCF(37,25) = HCF(173,37) = HCF(210,173) = HCF(383,210) .

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

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

781 = 1 x 781 + 0

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

Notice that 1 = HCF(781,1) .
