HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 743, 469, 195 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 743, 469, 195 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 743, 469, 195 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 743, 469, 195 is 1.
HCF(743, 469, 195) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 743, 469, 195 is 1.
Step 1: Since 743 > 469, we apply the division lemma to 743 and 469, to get
743 = 469 x 1 + 274
Step 2: Since the reminder 469 ≠ 0, we apply division lemma to 274 and 469, to get
469 = 274 x 1 + 195
Step 3: We consider the new divisor 274 and the new remainder 195, and apply the division lemma to get
274 = 195 x 1 + 79
We consider the new divisor 195 and the new remainder 79,and apply the division lemma to get
195 = 79 x 2 + 37
We consider the new divisor 79 and the new remainder 37,and apply the division lemma to get
79 = 37 x 2 + 5
We consider the new divisor 37 and the new remainder 5,and apply the division lemma to get
37 = 5 x 7 + 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 743 and 469 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(37,5) = HCF(79,37) = HCF(195,79) = HCF(274,195) = HCF(469,274) = HCF(743,469) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 195 > 1, we apply the division lemma to 195 and 1, to get
195 = 1 x 195 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 195 is 1
Notice that 1 = HCF(195,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 743, 469, 195?
Answer: HCF of 743, 469, 195 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 743, 469, 195 using Euclid's Algorithm?
Answer: For arbitrary numbers 743, 469, 195 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
