HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 239, 372, 71 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 239, 372, 71 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 239, 372, 71 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 239, 372, 71 is 1.
HCF(239, 372, 71) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 239, 372, 71 is 1.
Step 1: Since 372 > 239, we apply the division lemma to 372 and 239, to get
372 = 239 x 1 + 133
Step 2: Since the reminder 239 ≠ 0, we apply division lemma to 133 and 239, to get
239 = 133 x 1 + 106
Step 3: We consider the new divisor 133 and the new remainder 106, and apply the division lemma to get
133 = 106 x 1 + 27
We consider the new divisor 106 and the new remainder 27,and apply the division lemma to get
106 = 27 x 3 + 25
We consider the new divisor 27 and the new remainder 25,and apply the division lemma to get
27 = 25 x 1 + 2
We consider the new divisor 25 and the new remainder 2,and apply the division lemma to get
25 = 2 x 12 + 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 239 and 372 is 1
Notice that 1 = HCF(2,1) = HCF(25,2) = HCF(27,25) = HCF(106,27) = HCF(133,106) = HCF(239,133) = HCF(372,239) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 71 > 1, we apply the division lemma to 71 and 1, to get
71 = 1 x 71 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 71 is 1
Notice that 1 = HCF(71,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 239, 372, 71?
Answer: HCF of 239, 372, 71 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 239, 372, 71 using Euclid's Algorithm?
Answer: For arbitrary numbers 239, 372, 71 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
