HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 817, 993, 825 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 817, 993, 825 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 817, 993, 825 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 817, 993, 825 is 1.

HCF(817, 993, 825) = 1

HCF of 817, 993, 825 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 817, 993, 825 is 1.

Highest Common Factor of 817,993,825 using Euclid's algorithm

Highest Common Factor of 817,993,825 is 1

Step 1: Since 993 > 817, we apply the division lemma to 993 and 817, to get

993 = 817 x 1 + 176

Step 2: Since the reminder 817 ≠ 0, we apply division lemma to 176 and 817, to get

817 = 176 x 4 + 113

Step 3: We consider the new divisor 176 and the new remainder 113, and apply the division lemma to get

176 = 113 x 1 + 63

We consider the new divisor 113 and the new remainder 63,and apply the division lemma to get

113 = 63 x 1 + 50

We consider the new divisor 63 and the new remainder 50,and apply the division lemma to get

63 = 50 x 1 + 13

We consider the new divisor 50 and the new remainder 13,and apply the division lemma to get

50 = 13 x 3 + 11

We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get

13 = 11 x 1 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 817 and 993 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(50,13) = HCF(63,50) = HCF(113,63) = HCF(176,113) = HCF(817,176) = HCF(993,817) .


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

Step 1: Since 825 > 1, we apply the division lemma to 825 and 1, to get

825 = 1 x 825 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 825 is 1

Notice that 1 = HCF(825,1) .
