HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 269, 644, 393 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 269, 644, 393 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 269, 644, 393 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 269, 644, 393 is 1.
HCF(269, 644, 393) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 269, 644, 393 is 1.
Step 1: Since 644 > 269, we apply the division lemma to 644 and 269, to get
644 = 269 x 2 + 106
Step 2: Since the reminder 269 ≠ 0, we apply division lemma to 106 and 269, to get
269 = 106 x 2 + 57
Step 3: We consider the new divisor 106 and the new remainder 57, and apply the division lemma to get
106 = 57 x 1 + 49
We consider the new divisor 57 and the new remainder 49,and apply the division lemma to get
57 = 49 x 1 + 8
We consider the new divisor 49 and the new remainder 8,and apply the division lemma to get
49 = 8 x 6 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 269 and 644 is 1
Notice that 1 = HCF(8,1) = HCF(49,8) = HCF(57,49) = HCF(106,57) = HCF(269,106) = HCF(644,269) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 393 > 1, we apply the division lemma to 393 and 1, to get
393 = 1 x 393 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 393 is 1
Notice that 1 = HCF(393,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 269, 644, 393?
Answer: HCF of 269, 644, 393 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 269, 644, 393 using Euclid's Algorithm?
Answer: For arbitrary numbers 269, 644, 393 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
