HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 507, 717 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 507, 717 is 3 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 507, 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 507, 717 is 3.

HCF(507, 717) = 3

Highest Common Factor of 507,717 using Euclid's algorithm

Highest Common Factor of 507,717 is 3

Step 1: Since 717 > 507, we apply the division lemma to 717 and 507, to get

717 = 507 x 1 + 210

Step 2: Since the reminder 507 ≠ 0, we apply division lemma to 210 and 507, to get

507 = 210 x 2 + 87

Step 3: We consider the new divisor 210 and the new remainder 87, and apply the division lemma to get

210 = 87 x 2 + 36

We consider the new divisor 87 and the new remainder 36,and apply the division lemma to get

87 = 36 x 2 + 15

We consider the new divisor 36 and the new remainder 15,and apply the division lemma to get

36 = 15 x 2 + 6

We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get

15 = 6 x 2 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 507 and 717 is 3

Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(36,15) = HCF(87,36) = HCF(210,87) = HCF(507,210) = HCF(717,507) .
