HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 810, 3205 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 810, 3205 is 5 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 810, 3205 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 810, 3205 is 5.
HCF(810, 3205) = 5
HCF of 810, 3205 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 810, 3205 is 5.
Highest Common Factor of 810,3205 is 5
Step 1: Since 3205 > 810, we apply the division lemma to 3205 and 810, to get
3205 = 810 x 3 + 775
Step 2: Since the reminder 810 ≠ 0, we apply division lemma to 775 and 810, to get
810 = 775 x 1 + 35
Step 3: We consider the new divisor 775 and the new remainder 35, and apply the division lemma to get
775 = 35 x 22 + 5
We consider the new divisor 35 and the new remainder 5, and apply the division lemma to get
35 = 5 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 810 and 3205 is 5
Notice that 5 = HCF(35,5) = HCF(775,35) = HCF(810,775) = HCF(3205,810) .
