HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 531, 797, 919 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 531, 797, 919 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 531, 797, 919 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 531, 797, 919 is 1.
HCF(531, 797, 919) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 531, 797, 919 is 1.
Step 1: Since 797 > 531, we apply the division lemma to 797 and 531, to get
797 = 531 x 1 + 266
Step 2: Since the reminder 531 ≠ 0, we apply division lemma to 266 and 531, to get
531 = 266 x 1 + 265
Step 3: We consider the new divisor 266 and the new remainder 265, and apply the division lemma to get
266 = 265 x 1 + 1
We consider the new divisor 265 and the new remainder 1, and apply the division lemma to get
265 = 1 x 265 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 531 and 797 is 1
Notice that 1 = HCF(265,1) = HCF(266,265) = HCF(531,266) = HCF(797,531) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 919 > 1, we apply the division lemma to 919 and 1, to get
919 = 1 x 919 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 919 is 1
Notice that 1 = HCF(919,1) .
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 531, 797, 919?
Answer: HCF of 531, 797, 919 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 531, 797, 919 using Euclid's Algorithm?
Answer: For arbitrary numbers 531, 797, 919 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
