HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 813, 151, 731 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 813, 151, 731 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 813, 151, 731 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 813, 151, 731 is 1.
HCF(813, 151, 731) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 813, 151, 731 is 1.
Step 1: Since 813 > 151, we apply the division lemma to 813 and 151, to get
813 = 151 x 5 + 58
Step 2: Since the reminder 151 ≠ 0, we apply division lemma to 58 and 151, to get
151 = 58 x 2 + 35
Step 3: We consider the new divisor 58 and the new remainder 35, and apply the division lemma to get
58 = 35 x 1 + 23
We consider the new divisor 35 and the new remainder 23,and apply the division lemma to get
35 = 23 x 1 + 12
We consider the new divisor 23 and the new remainder 12,and apply the division lemma to get
23 = 12 x 1 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 813 and 151 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(23,12) = HCF(35,23) = HCF(58,35) = HCF(151,58) = HCF(813,151) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 731 > 1, we apply the division lemma to 731 and 1, to get
731 = 1 x 731 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 731 is 1
Notice that 1 = HCF(731,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 813, 151, 731?
Answer: HCF of 813, 151, 731 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 813, 151, 731 using Euclid's Algorithm?
Answer: For arbitrary numbers 813, 151, 731 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
