HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 6475, 822 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 6475, 822 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 6475, 822 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 6475, 822 is 1.
HCF(6475, 822) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 6475, 822 is 1.
Step 1: Since 6475 > 822, we apply the division lemma to 6475 and 822, to get
6475 = 822 x 7 + 721
Step 2: Since the reminder 822 ≠ 0, we apply division lemma to 721 and 822, to get
822 = 721 x 1 + 101
Step 3: We consider the new divisor 721 and the new remainder 101, and apply the division lemma to get
721 = 101 x 7 + 14
We consider the new divisor 101 and the new remainder 14,and apply the division lemma to get
101 = 14 x 7 + 3
We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get
14 = 3 x 4 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 6475 and 822 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(101,14) = HCF(721,101) = HCF(822,721) = HCF(6475,822) .
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 6475, 822?
Answer: HCF of 6475, 822 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 6475, 822 using Euclid's Algorithm?
Answer: For arbitrary numbers 6475, 822 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
