HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 507, 315, 783 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 507, 315, 783 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, 315, 783 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, 315, 783 is 3.

HCF(507, 315, 783) = 3

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 507, 315, 783 is 3.

Highest Common Factor of 507,315,783 using Euclid's algorithm

Highest Common Factor of 507,315,783 is 3

Step 1: Since 507 > 315, we apply the division lemma to 507 and 315, to get

507 = 315 x 1 + 192

Step 2: Since the reminder 315 ≠ 0, we apply division lemma to 192 and 315, to get

315 = 192 x 1 + 123

Step 3: We consider the new divisor 192 and the new remainder 123, and apply the division lemma to get

192 = 123 x 1 + 69

We consider the new divisor 123 and the new remainder 69,and apply the division lemma to get

123 = 69 x 1 + 54

We consider the new divisor 69 and the new remainder 54,and apply the division lemma to get

69 = 54 x 1 + 15

We consider the new divisor 54 and the new remainder 15,and apply the division lemma to get

54 = 15 x 3 + 9

We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get

15 = 9 x 1 + 6

We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get

9 = 6 x 1 + 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 315 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(54,15) = HCF(69,54) = HCF(123,69) = HCF(192,123) = HCF(315,192) = HCF(507,315) .


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

Step 1: Since 783 > 3, we apply the division lemma to 783 and 3, to get

783 = 3 x 261 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 783 is 3

Notice that 3 = HCF(783,3) .
