HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 191, 804, 781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 191, 804, 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 191, 804, 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 191, 804, 781 is 1.

HCF(191, 804, 781) = 1

Highest common factor (HCF) of 191, 804, 781 is 1.

Highest Common Factor of 191,804,781 using Euclid's algorithm

Highest Common Factor of 191,804,781 is 1

Step 1: Since 804 > 191, we apply the division lemma to 804 and 191, to get

804 = 191 x 4 + 40

Step 2: Since the reminder 191 ≠ 0, we apply division lemma to 40 and 191, to get

191 = 40 x 4 + 31

Step 3: We consider the new divisor 40 and the new remainder 31, and apply the division lemma to get

40 = 31 x 1 + 9

We consider the new divisor 31 and the new remainder 9,and apply the division lemma to get

31 = 9 x 3 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 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 191 and 804 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(31,9) = HCF(40,31) = HCF(191,40) = HCF(804,191) .

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) .
