HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 517, 8242, 8070 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 517, 8242, 8070 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, 8242, 8070 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, 8242, 8070 is 1.
HCF(517, 8242, 8070) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 517, 8242, 8070 is 1.
Step 1: Since 8242 > 517, we apply the division lemma to 8242 and 517, to get
8242 = 517 x 15 + 487
Step 2: Since the reminder 517 ≠ 0, we apply division lemma to 487 and 517, to get
517 = 487 x 1 + 30
Step 3: We consider the new divisor 487 and the new remainder 30, and apply the division lemma to get
487 = 30 x 16 + 7
We consider the new divisor 30 and the new remainder 7,and apply the division lemma to get
30 = 7 x 4 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 8242 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(30,7) = HCF(487,30) = HCF(517,487) = HCF(8242,517) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 8070 > 1, we apply the division lemma to 8070 and 1, to get
8070 = 1 x 8070 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 8070 is 1
Notice that 1 = HCF(8070,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
