HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 431, 218, 230 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 431, 218, 230 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 431, 218, 230 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 431, 218, 230 is 1.
HCF(431, 218, 230) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 431, 218, 230 is 1.
Step 1: Since 431 > 218, we apply the division lemma to 431 and 218, to get
431 = 218 x 1 + 213
Step 2: Since the reminder 218 ≠ 0, we apply division lemma to 213 and 218, to get
218 = 213 x 1 + 5
Step 3: We consider the new divisor 213 and the new remainder 5, and apply the division lemma to get
213 = 5 x 42 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 431 and 218 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(213,5) = HCF(218,213) = HCF(431,218) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 230 > 1, we apply the division lemma to 230 and 1, to get
230 = 1 x 230 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 230 is 1
Notice that 1 = HCF(230,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 431, 218, 230?
Answer: HCF of 431, 218, 230 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 431, 218, 230 using Euclid's Algorithm?
Answer: For arbitrary numbers 431, 218, 230 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
