HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 238, 428, 396, 775 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 238, 428, 396, 775 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 238, 428, 396, 775 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 238, 428, 396, 775 is 1.
HCF(238, 428, 396, 775) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 238, 428, 396, 775 is 1.
Step 1: Since 428 > 238, we apply the division lemma to 428 and 238, to get
428 = 238 x 1 + 190
Step 2: Since the reminder 238 ≠ 0, we apply division lemma to 190 and 238, to get
238 = 190 x 1 + 48
Step 3: We consider the new divisor 190 and the new remainder 48, and apply the division lemma to get
190 = 48 x 3 + 46
We consider the new divisor 48 and the new remainder 46,and apply the division lemma to get
48 = 46 x 1 + 2
We consider the new divisor 46 and the new remainder 2,and apply the division lemma to get
46 = 2 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 238 and 428 is 2
Notice that 2 = HCF(46,2) = HCF(48,46) = HCF(190,48) = HCF(238,190) = HCF(428,238) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 396 > 2, we apply the division lemma to 396 and 2, to get
396 = 2 x 198 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 396 is 2
Notice that 2 = HCF(396,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 775 > 2, we apply the division lemma to 775 and 2, to get
775 = 2 x 387 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 775 is 1
Notice that 1 = HCF(2,1) = HCF(775,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 238, 428, 396, 775?
Answer: HCF of 238, 428, 396, 775 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 238, 428, 396, 775 using Euclid's Algorithm?
Answer: For arbitrary numbers 238, 428, 396, 775 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
