HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 331, 443, 225 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 331, 443, 225 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 331, 443, 225 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 331, 443, 225 is 1.
HCF(331, 443, 225) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 331, 443, 225 is 1.
Step 1: Since 443 > 331, we apply the division lemma to 443 and 331, to get
443 = 331 x 1 + 112
Step 2: Since the reminder 331 ≠ 0, we apply division lemma to 112 and 331, to get
331 = 112 x 2 + 107
Step 3: We consider the new divisor 112 and the new remainder 107, and apply the division lemma to get
112 = 107 x 1 + 5
We consider the new divisor 107 and the new remainder 5,and apply the division lemma to get
107 = 5 x 21 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 331 and 443 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(107,5) = HCF(112,107) = HCF(331,112) = HCF(443,331) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 225 > 1, we apply the division lemma to 225 and 1, to get
225 = 1 x 225 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 225 is 1
Notice that 1 = HCF(225,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 331, 443, 225?
Answer: HCF of 331, 443, 225 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 331, 443, 225 using Euclid's Algorithm?
Answer: For arbitrary numbers 331, 443, 225 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
