HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 986, 563 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 986, 563 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 986, 563 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 986, 563 is 1.
HCF(986, 563) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 986, 563 is 1.
Step 1: Since 986 > 563, we apply the division lemma to 986 and 563, to get
986 = 563 x 1 + 423
Step 2: Since the reminder 563 ≠ 0, we apply division lemma to 423 and 563, to get
563 = 423 x 1 + 140
Step 3: We consider the new divisor 423 and the new remainder 140, and apply the division lemma to get
423 = 140 x 3 + 3
We consider the new divisor 140 and the new remainder 3,and apply the division lemma to get
140 = 3 x 46 + 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 986 and 563 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(140,3) = HCF(423,140) = HCF(563,423) = HCF(986,563) .
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 986, 563?
Answer: HCF of 986, 563 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 986, 563 using Euclid's Algorithm?
Answer: For arbitrary numbers 986, 563 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
