HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 798, 458, 844 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 798, 458, 844 is 2 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, 458, 844 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, 458, 844 is 2.

HCF(798, 458, 844) = 2

HCF of 798, 458, 844 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, 458, 844 is 2.

Highest Common Factor of 798,458,844 using Euclid's algorithm

Highest Common Factor of 798,458,844 is 2

Step 1: Since 798 > 458, we apply the division lemma to 798 and 458, to get

798 = 458 x 1 + 340

Step 2: Since the reminder 458 ≠ 0, we apply division lemma to 340 and 458, to get

458 = 340 x 1 + 118

Step 3: We consider the new divisor 340 and the new remainder 118, and apply the division lemma to get

340 = 118 x 2 + 104

We consider the new divisor 118 and the new remainder 104,and apply the division lemma to get

118 = 104 x 1 + 14

We consider the new divisor 104 and the new remainder 14,and apply the division lemma to get

104 = 14 x 7 + 6

We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get

14 = 6 x 2 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 798 and 458 is 2

Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(104,14) = HCF(118,104) = HCF(340,118) = HCF(458,340) = HCF(798,458) .

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

Step 1: Since 844 > 2, we apply the division lemma to 844 and 2, to get

844 = 2 x 422 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 844 is 2

Notice that 2 = HCF(844,2) .
