HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 838, 961 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 838, 961 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 838, 961 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 838, 961 is 1.
HCF(838, 961) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 838, 961 is 1.
Step 1: Since 961 > 838, we apply the division lemma to 961 and 838, to get
961 = 838 x 1 + 123
Step 2: Since the reminder 838 ≠ 0, we apply division lemma to 123 and 838, to get
838 = 123 x 6 + 100
Step 3: We consider the new divisor 123 and the new remainder 100, and apply the division lemma to get
123 = 100 x 1 + 23
We consider the new divisor 100 and the new remainder 23,and apply the division lemma to get
100 = 23 x 4 + 8
We consider the new divisor 23 and the new remainder 8,and apply the division lemma to get
23 = 8 x 2 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 838 and 961 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(23,8) = HCF(100,23) = HCF(123,100) = HCF(838,123) = HCF(961,838) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
Answer: Euclid's Division Algorithm is a technique to compute the Highest Common Factor (HCF) of given positive integers.
2. what is the HCF of 838, 961?
Answer: HCF of 838, 961 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 838, 961 using Euclid's Algorithm?
Answer: For arbitrary numbers 838, 961 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
