HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 551, 807 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 551, 807 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 551, 807 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 551, 807 is 1.
HCF(551, 807) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 551, 807 is 1.
Step 1: Since 807 > 551, we apply the division lemma to 807 and 551, to get
807 = 551 x 1 + 256
Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 256 and 551, to get
551 = 256 x 2 + 39
Step 3: We consider the new divisor 256 and the new remainder 39, and apply the division lemma to get
256 = 39 x 6 + 22
We consider the new divisor 39 and the new remainder 22,and apply the division lemma to get
39 = 22 x 1 + 17
We consider the new divisor 22 and the new remainder 17,and apply the division lemma to get
22 = 17 x 1 + 5
We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get
17 = 5 x 3 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 551 and 807 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(22,17) = HCF(39,22) = HCF(256,39) = HCF(551,256) = HCF(807,551) .
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 551, 807?
Answer: HCF of 551, 807 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 551, 807 using Euclid's Algorithm?
Answer: For arbitrary numbers 551, 807 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
