HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 717, 230, 390 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 717, 230, 390 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 717, 230, 390 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 717, 230, 390 is 1.

HCF(717, 230, 390) = 1

HCF of 717, 230, 390 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 717, 230, 390 is 1.

Highest Common Factor of 717,230,390 using Euclid's algorithm

Highest Common Factor of 717,230,390 is 1

Step 1: Since 717 > 230, we apply the division lemma to 717 and 230, to get

717 = 230 x 3 + 27

Step 2: Since the reminder 230 ≠ 0, we apply division lemma to 27 and 230, to get

230 = 27 x 8 + 14

Step 3: We consider the new divisor 27 and the new remainder 14, and apply the division lemma to get

27 = 14 x 1 + 13

We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get

14 = 13 x 1 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 717 and 230 is 1

Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(27,14) = HCF(230,27) = HCF(717,230) .

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

Step 1: Since 390 > 1, we apply the division lemma to 390 and 1, to get

390 = 1 x 390 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 390 is 1

Notice that 1 = HCF(390,1) .
