HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 798, 809 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 798, 809 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, 809 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, 809 is 1.
HCF(798, 809) = 1
HCF of 798, 809 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, 809 is 1.
Highest Common Factor of 798,809 is 1
Step 1: Since 809 > 798, we apply the division lemma to 809 and 798, to get
809 = 798 x 1 + 11
Step 2: Since the reminder 798 ≠ 0, we apply division lemma to 11 and 798, to get
798 = 11 x 72 + 6
Step 3: We consider the new divisor 11 and the new remainder 6, and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 798 and 809 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(798,11) = HCF(809,798) .
