HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 530, 997 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 530, 997 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 530, 997 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 530, 997 is 1.
HCF(530, 997) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 530, 997 is 1.
Step 1: Since 997 > 530, we apply the division lemma to 997 and 530, to get
997 = 530 x 1 + 467
Step 2: Since the reminder 530 ≠ 0, we apply division lemma to 467 and 530, to get
530 = 467 x 1 + 63
Step 3: We consider the new divisor 467 and the new remainder 63, and apply the division lemma to get
467 = 63 x 7 + 26
We consider the new divisor 63 and the new remainder 26,and apply the division lemma to get
63 = 26 x 2 + 11
We consider the new divisor 26 and the new remainder 11,and apply the division lemma to get
26 = 11 x 2 + 4
We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get
11 = 4 x 2 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 530 and 997 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(26,11) = HCF(63,26) = HCF(467,63) = HCF(530,467) = HCF(997,530) .
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 530, 997?
Answer: HCF of 530, 997 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 530, 997 using Euclid's Algorithm?
Answer: For arbitrary numbers 530, 997 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
