HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 7026, 9098 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 855, 7026, 9098 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 855, 7026, 9098 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 855, 7026, 9098 is 1.

HCF(855, 7026, 9098) = 1

HCF of 855, 7026, 9098 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 855, 7026, 9098 is 1.

Highest Common Factor of 855,7026,9098 using Euclid's algorithm

Highest Common Factor of 855,7026,9098 is 1

Step 1: Since 7026 > 855, we apply the division lemma to 7026 and 855, to get

7026 = 855 x 8 + 186

Step 2: Since the reminder 855 ≠ 0, we apply division lemma to 186 and 855, to get

855 = 186 x 4 + 111

Step 3: We consider the new divisor 186 and the new remainder 111, and apply the division lemma to get

186 = 111 x 1 + 75

We consider the new divisor 111 and the new remainder 75,and apply the division lemma to get

111 = 75 x 1 + 36

We consider the new divisor 75 and the new remainder 36,and apply the division lemma to get

75 = 36 x 2 + 3

We consider the new divisor 36 and the new remainder 3,and apply the division lemma to get

36 = 3 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 855 and 7026 is 3

Notice that 3 = HCF(36,3) = HCF(75,36) = HCF(111,75) = HCF(186,111) = HCF(855,186) = HCF(7026,855) .


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

Step 1: Since 9098 > 3, we apply the division lemma to 9098 and 3, to get

9098 = 3 x 3032 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 9098 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(9098,3) .
