HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 691, 250, 944 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 691, 250, 944 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 691, 250, 944 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 691, 250, 944 is 1.

HCF(691, 250, 944) = 1

HCF of 691, 250, 944 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 691, 250, 944 is 1.

Highest Common Factor of 691,250,944 using Euclid's algorithm

Highest Common Factor of 691,250,944 is 1

Step 1: Since 691 > 250, we apply the division lemma to 691 and 250, to get

691 = 250 x 2 + 191

Step 2: Since the reminder 250 ≠ 0, we apply division lemma to 191 and 250, to get

250 = 191 x 1 + 59

Step 3: We consider the new divisor 191 and the new remainder 59, and apply the division lemma to get

191 = 59 x 3 + 14

We consider the new divisor 59 and the new remainder 14,and apply the division lemma to get

59 = 14 x 4 + 3

We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get

14 = 3 x 4 + 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 691 and 250 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(59,14) = HCF(191,59) = HCF(250,191) = HCF(691,250) .

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

Step 1: Since 944 > 1, we apply the division lemma to 944 and 1, to get

944 = 1 x 944 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 944 is 1

Notice that 1 = HCF(944,1) .
