HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 508, 775, 644 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 508, 775, 644 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 508, 775, 644 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 508, 775, 644 is 1.
HCF(508, 775, 644) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 508, 775, 644 is 1.
Step 1: Since 775 > 508, we apply the division lemma to 775 and 508, to get
775 = 508 x 1 + 267
Step 2: Since the reminder 508 ≠ 0, we apply division lemma to 267 and 508, to get
508 = 267 x 1 + 241
Step 3: We consider the new divisor 267 and the new remainder 241, and apply the division lemma to get
267 = 241 x 1 + 26
We consider the new divisor 241 and the new remainder 26,and apply the division lemma to get
241 = 26 x 9 + 7
We consider the new divisor 26 and the new remainder 7,and apply the division lemma to get
26 = 7 x 3 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 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 508 and 775 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(26,7) = HCF(241,26) = HCF(267,241) = HCF(508,267) = HCF(775,508) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 644 > 1, we apply the division lemma to 644 and 1, to get
644 = 1 x 644 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 644 is 1
Notice that 1 = HCF(644,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 508, 775, 644?
Answer: HCF of 508, 775, 644 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 508, 775, 644 using Euclid's Algorithm?
Answer: For arbitrary numbers 508, 775, 644 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
