HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 805, 47415 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 805, 47415 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 805, 47415 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 805, 47415 is 5.
HCF(805, 47415) = 5
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 805, 47415 is 5.
Step 1: Since 47415 > 805, we apply the division lemma to 47415 and 805, to get
47415 = 805 x 58 + 725
Step 2: Since the reminder 805 ≠ 0, we apply division lemma to 725 and 805, to get
805 = 725 x 1 + 80
Step 3: We consider the new divisor 725 and the new remainder 80, and apply the division lemma to get
725 = 80 x 9 + 5
We consider the new divisor 80 and the new remainder 5, and apply the division lemma to get
80 = 5 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 805 and 47415 is 5
Notice that 5 = HCF(80,5) = HCF(725,80) = HCF(805,725) = HCF(47415,805) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 805, 47415?
Answer: HCF of 805, 47415 is 5 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 805, 47415 using Euclid's Algorithm?
Answer: For arbitrary numbers 805, 47415 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
