HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 809, 985 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 809, 985 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 809, 985 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 809, 985 is 1.
HCF(809, 985) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 809, 985 is 1.
Step 1: Since 985 > 809, we apply the division lemma to 985 and 809, to get
985 = 809 x 1 + 176
Step 2: Since the reminder 809 ≠ 0, we apply division lemma to 176 and 809, to get
809 = 176 x 4 + 105
Step 3: We consider the new divisor 176 and the new remainder 105, and apply the division lemma to get
176 = 105 x 1 + 71
We consider the new divisor 105 and the new remainder 71,and apply the division lemma to get
105 = 71 x 1 + 34
We consider the new divisor 71 and the new remainder 34,and apply the division lemma to get
71 = 34 x 2 + 3
We consider the new divisor 34 and the new remainder 3,and apply the division lemma to get
34 = 3 x 11 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 809 and 985 is 1
Notice that 1 = HCF(3,1) = HCF(34,3) = HCF(71,34) = HCF(105,71) = HCF(176,105) = HCF(809,176) = HCF(985,809) .
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 809, 985?
Answer: HCF of 809, 985 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 809, 985 using Euclid's Algorithm?
Answer: For arbitrary numbers 809, 985 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
