HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 417, 644, 762 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 417, 644, 762 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 417, 644, 762 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 417, 644, 762 is 1.
HCF(417, 644, 762) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 417, 644, 762 is 1.
Step 1: Since 644 > 417, we apply the division lemma to 644 and 417, to get
644 = 417 x 1 + 227
Step 2: Since the reminder 417 ≠ 0, we apply division lemma to 227 and 417, to get
417 = 227 x 1 + 190
Step 3: We consider the new divisor 227 and the new remainder 190, and apply the division lemma to get
227 = 190 x 1 + 37
We consider the new divisor 190 and the new remainder 37,and apply the division lemma to get
190 = 37 x 5 + 5
We consider the new divisor 37 and the new remainder 5,and apply the division lemma to get
37 = 5 x 7 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 417 and 644 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(37,5) = HCF(190,37) = HCF(227,190) = HCF(417,227) = HCF(644,417) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 762 > 1, we apply the division lemma to 762 and 1, to get
762 = 1 x 762 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 762 is 1
Notice that 1 = HCF(762,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 417, 644, 762?
Answer: HCF of 417, 644, 762 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 417, 644, 762 using Euclid's Algorithm?
Answer: For arbitrary numbers 417, 644, 762 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
