HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 798, 502, 915 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 798, 502, 915 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 798, 502, 915 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 798, 502, 915 is 1.

HCF(798, 502, 915) = 1

HCF of 798, 502, 915 using Euclid's algorithm

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

Highest common factor (HCF) of 798, 502, 915 is 1.

Highest Common Factor of 798,502,915 using Euclid's algorithm

Highest Common Factor of 798,502,915 is 1

Step 1: Since 798 > 502, we apply the division lemma to 798 and 502, to get

798 = 502 x 1 + 296

Step 2: Since the reminder 502 ≠ 0, we apply division lemma to 296 and 502, to get

502 = 296 x 1 + 206

Step 3: We consider the new divisor 296 and the new remainder 206, and apply the division lemma to get

296 = 206 x 1 + 90

We consider the new divisor 206 and the new remainder 90,and apply the division lemma to get

206 = 90 x 2 + 26

We consider the new divisor 90 and the new remainder 26,and apply the division lemma to get

90 = 26 x 3 + 12

We consider the new divisor 26 and the new remainder 12,and apply the division lemma to get

26 = 12 x 2 + 2

We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get

12 = 2 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 798 and 502 is 2

Notice that 2 = HCF(12,2) = HCF(26,12) = HCF(90,26) = HCF(206,90) = HCF(296,206) = HCF(502,296) = HCF(798,502) .


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

Step 1: Since 915 > 2, we apply the division lemma to 915 and 2, to get

915 = 2 x 457 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 915 is 1

Notice that 1 = HCF(2,1) = HCF(915,2) .
