HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 917, 572, 417 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 917, 572, 417 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 917, 572, 417 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 917, 572, 417 is 1.
HCF(917, 572, 417) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 917, 572, 417 is 1.
Step 1: Since 917 > 572, we apply the division lemma to 917 and 572, to get
917 = 572 x 1 + 345
Step 2: Since the reminder 572 ≠ 0, we apply division lemma to 345 and 572, to get
572 = 345 x 1 + 227
Step 3: We consider the new divisor 345 and the new remainder 227, and apply the division lemma to get
345 = 227 x 1 + 118
We consider the new divisor 227 and the new remainder 118,and apply the division lemma to get
227 = 118 x 1 + 109
We consider the new divisor 118 and the new remainder 109,and apply the division lemma to get
118 = 109 x 1 + 9
We consider the new divisor 109 and the new remainder 9,and apply the division lemma to get
109 = 9 x 12 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 917 and 572 is 1
Notice that 1 = HCF(9,1) = HCF(109,9) = HCF(118,109) = HCF(227,118) = HCF(345,227) = HCF(572,345) = HCF(917,572) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 417 > 1, we apply the division lemma to 417 and 1, to get
417 = 1 x 417 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 417 is 1
Notice that 1 = HCF(417,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 917, 572, 417?
Answer: HCF of 917, 572, 417 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 917, 572, 417 using Euclid's Algorithm?
Answer: For arbitrary numbers 917, 572, 417 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
