HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 6890, 917 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 6890, 917 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 6890, 917 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 6890, 917 is 1.
HCF(6890, 917) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 6890, 917 is 1.
Step 1: Since 6890 > 917, we apply the division lemma to 6890 and 917, to get
6890 = 917 x 7 + 471
Step 2: Since the reminder 917 ≠ 0, we apply division lemma to 471 and 917, to get
917 = 471 x 1 + 446
Step 3: We consider the new divisor 471 and the new remainder 446, and apply the division lemma to get
471 = 446 x 1 + 25
We consider the new divisor 446 and the new remainder 25,and apply the division lemma to get
446 = 25 x 17 + 21
We consider the new divisor 25 and the new remainder 21,and apply the division lemma to get
25 = 21 x 1 + 4
We consider the new divisor 21 and the new remainder 4,and apply the division lemma to get
21 = 4 x 5 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6890 and 917 is 1
Notice that 1 = HCF(4,1) = HCF(21,4) = HCF(25,21) = HCF(446,25) = HCF(471,446) = HCF(917,471) = HCF(6890,917) .
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 6890, 917?
Answer: HCF of 6890, 917 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 6890, 917 using Euclid's Algorithm?
Answer: For arbitrary numbers 6890, 917 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
