HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 503, 694, 82 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 503, 694, 82 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 503, 694, 82 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 503, 694, 82 is 1.

HCF(503, 694, 82) = 1

Highest common factor (HCF) of 503, 694, 82 is 1.

Highest Common Factor of 503,694,82 using Euclid's algorithm

Highest Common Factor of 503,694,82 is 1

Step 1: Since 694 > 503, we apply the division lemma to 694 and 503, to get

694 = 503 x 1 + 191

Step 2: Since the reminder 503 ≠ 0, we apply division lemma to 191 and 503, to get

503 = 191 x 2 + 121

Step 3: We consider the new divisor 191 and the new remainder 121, and apply the division lemma to get

191 = 121 x 1 + 70

We consider the new divisor 121 and the new remainder 70,and apply the division lemma to get

121 = 70 x 1 + 51

We consider the new divisor 70 and the new remainder 51,and apply the division lemma to get

70 = 51 x 1 + 19

We consider the new divisor 51 and the new remainder 19,and apply the division lemma to get

51 = 19 x 2 + 13

We consider the new divisor 19 and the new remainder 13,and apply the division lemma to get

19 = 13 x 1 + 6

We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get

13 = 6 x 2 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 503 and 694 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(19,13) = HCF(51,19) = HCF(70,51) = HCF(121,70) = HCF(191,121) = HCF(503,191) = HCF(694,503) .


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

Step 1: Since 82 > 1, we apply the division lemma to 82 and 1, to get

82 = 1 x 82 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 82 is 1

Notice that 1 = HCF(82,1) .
