HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 135, 424, 38, 438 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 135, 424, 38, 438 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 135, 424, 38, 438 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 135, 424, 38, 438 is 1.
HCF(135, 424, 38, 438) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 135, 424, 38, 438 is 1.
Step 1: Since 424 > 135, we apply the division lemma to 424 and 135, to get
424 = 135 x 3 + 19
Step 2: Since the reminder 135 ≠ 0, we apply division lemma to 19 and 135, to get
135 = 19 x 7 + 2
Step 3: We consider the new divisor 19 and the new remainder 2, and apply the division lemma to get
19 = 2 x 9 + 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 135 and 424 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(135,19) = HCF(424,135) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 38 > 1, we apply the division lemma to 38 and 1, to get
38 = 1 x 38 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 38 is 1
Notice that 1 = HCF(38,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 438 > 1, we apply the division lemma to 438 and 1, to get
438 = 1 x 438 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 438 is 1
Notice that 1 = HCF(438,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 135, 424, 38, 438?
Answer: HCF of 135, 424, 38, 438 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 135, 424, 38, 438 using Euclid's Algorithm?
Answer: For arbitrary numbers 135, 424, 38, 438 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
