HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 505, 710, 896, 85 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 505, 710, 896, 85 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 505, 710, 896, 85 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 505, 710, 896, 85 is 1.
HCF(505, 710, 896, 85) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 505, 710, 896, 85 is 1.
Step 1: Since 710 > 505, we apply the division lemma to 710 and 505, to get
710 = 505 x 1 + 205
Step 2: Since the reminder 505 ≠ 0, we apply division lemma to 205 and 505, to get
505 = 205 x 2 + 95
Step 3: We consider the new divisor 205 and the new remainder 95, and apply the division lemma to get
205 = 95 x 2 + 15
We consider the new divisor 95 and the new remainder 15,and apply the division lemma to get
95 = 15 x 6 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 505 and 710 is 5
Notice that 5 = HCF(15,5) = HCF(95,15) = HCF(205,95) = HCF(505,205) = HCF(710,505) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 896 > 5, we apply the division lemma to 896 and 5, to get
896 = 5 x 179 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, 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 5 and 896 is 1
Notice that 1 = HCF(5,1) = HCF(896,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 85 > 1, we apply the division lemma to 85 and 1, to get
85 = 1 x 85 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 85 is 1
Notice that 1 = HCF(85,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 505, 710, 896, 85?
Answer: HCF of 505, 710, 896, 85 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 505, 710, 896, 85 using Euclid's Algorithm?
Answer: For arbitrary numbers 505, 710, 896, 85 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
