HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 800, 865 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 800, 865 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 800, 865 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 800, 865 is 5.
HCF(800, 865) = 5
HCF of 800, 865 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 800, 865 is 5.
Highest Common Factor of 800,865 is 5
Step 1: Since 865 > 800, we apply the division lemma to 865 and 800, to get
865 = 800 x 1 + 65
Step 2: Since the reminder 800 ≠ 0, we apply division lemma to 65 and 800, to get
800 = 65 x 12 + 20
Step 3: We consider the new divisor 65 and the new remainder 20, and apply the division lemma to get
65 = 20 x 3 + 5
We consider the new divisor 20 and the new remainder 5, and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 800 and 865 is 5
Notice that 5 = HCF(20,5) = HCF(65,20) = HCF(800,65) = HCF(865,800) .
