HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 517, 897, 530 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 517, 897, 530 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 517, 897, 530 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 517, 897, 530 is 1.
HCF(517, 897, 530) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 517, 897, 530 is 1.
Step 1: Since 897 > 517, we apply the division lemma to 897 and 517, to get
897 = 517 x 1 + 380
Step 2: Since the reminder 517 ≠ 0, we apply division lemma to 380 and 517, to get
517 = 380 x 1 + 137
Step 3: We consider the new divisor 380 and the new remainder 137, and apply the division lemma to get
380 = 137 x 2 + 106
We consider the new divisor 137 and the new remainder 106,and apply the division lemma to get
137 = 106 x 1 + 31
We consider the new divisor 106 and the new remainder 31,and apply the division lemma to get
106 = 31 x 3 + 13
We consider the new divisor 31 and the new remainder 13,and apply the division lemma to get
31 = 13 x 2 + 5
We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get
13 = 5 x 2 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 517 and 897 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(31,13) = HCF(106,31) = HCF(137,106) = HCF(380,137) = HCF(517,380) = HCF(897,517) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 530 > 1, we apply the division lemma to 530 and 1, to get
530 = 1 x 530 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 530 is 1
Notice that 1 = HCF(530,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
