HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 837, 749, 813 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 837, 749, 813 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 837, 749, 813 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 837, 749, 813 is 1.
HCF(837, 749, 813) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 837, 749, 813 is 1.
Step 1: Since 837 > 749, we apply the division lemma to 837 and 749, to get
837 = 749 x 1 + 88
Step 2: Since the reminder 749 ≠ 0, we apply division lemma to 88 and 749, to get
749 = 88 x 8 + 45
Step 3: We consider the new divisor 88 and the new remainder 45, and apply the division lemma to get
88 = 45 x 1 + 43
We consider the new divisor 45 and the new remainder 43,and apply the division lemma to get
45 = 43 x 1 + 2
We consider the new divisor 43 and the new remainder 2,and apply the division lemma to get
43 = 2 x 21 + 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 837 and 749 is 1
Notice that 1 = HCF(2,1) = HCF(43,2) = HCF(45,43) = HCF(88,45) = HCF(749,88) = HCF(837,749) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 813 > 1, we apply the division lemma to 813 and 1, to get
813 = 1 x 813 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 813 is 1
Notice that 1 = HCF(813,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 837, 749, 813?
Answer: HCF of 837, 749, 813 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 837, 749, 813 using Euclid's Algorithm?
Answer: For arbitrary numbers 837, 749, 813 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
