HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 838, 717 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 838, 717 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 838, 717 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 838, 717 is 1.

HCF(838, 717) = 1

HCF of 838, 717 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 838, 717 is 1.

Highest Common Factor of 838,717 using Euclid's algorithm

Highest Common Factor of 838,717 is 1

Step 1: Since 838 > 717, we apply the division lemma to 838 and 717, to get

838 = 717 x 1 + 121

Step 2: Since the reminder 717 ≠ 0, we apply division lemma to 121 and 717, to get

717 = 121 x 5 + 112

Step 3: We consider the new divisor 121 and the new remainder 112, and apply the division lemma to get

121 = 112 x 1 + 9

We consider the new divisor 112 and the new remainder 9,and apply the division lemma to get

112 = 9 x 12 + 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 838 and 717 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(112,9) = HCF(121,112) = HCF(717,121) = HCF(838,717) .
