HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1311, 844 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1311, 844 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 1311, 844 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 1311, 844 is 1.
HCF(1311, 844) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1311, 844 is 1.
Step 1: Since 1311 > 844, we apply the division lemma to 1311 and 844, to get
1311 = 844 x 1 + 467
Step 2: Since the reminder 844 ≠ 0, we apply division lemma to 467 and 844, to get
844 = 467 x 1 + 377
Step 3: We consider the new divisor 467 and the new remainder 377, and apply the division lemma to get
467 = 377 x 1 + 90
We consider the new divisor 377 and the new remainder 90,and apply the division lemma to get
377 = 90 x 4 + 17
We consider the new divisor 90 and the new remainder 17,and apply the division lemma to get
90 = 17 x 5 + 5
We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get
17 = 5 x 3 + 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 1311 and 844 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(90,17) = HCF(377,90) = HCF(467,377) = HCF(844,467) = HCF(1311,844) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 1311, 844?
Answer: HCF of 1311, 844 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 1311, 844 using Euclid's Algorithm?
Answer: For arbitrary numbers 1311, 844 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
