HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 817, 530 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 817, 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 817, 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 817, 530 is 1.
HCF(817, 530) = 1
HCF of 817, 530 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 817, 530 is 1.
Highest Common Factor of 817,530 is 1
Step 1: Since 817 > 530, we apply the division lemma to 817 and 530, to get
817 = 530 x 1 + 287
Step 2: Since the reminder 530 ≠ 0, we apply division lemma to 287 and 530, to get
530 = 287 x 1 + 243
Step 3: We consider the new divisor 287 and the new remainder 243, and apply the division lemma to get
287 = 243 x 1 + 44
We consider the new divisor 243 and the new remainder 44,and apply the division lemma to get
243 = 44 x 5 + 23
We consider the new divisor 44 and the new remainder 23,and apply the division lemma to get
44 = 23 x 1 + 21
We consider the new divisor 23 and the new remainder 21,and apply the division lemma to get
23 = 21 x 1 + 2
We consider the new divisor 21 and the new remainder 2,and apply the division lemma to get
21 = 2 x 10 + 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 817 and 530 is 1
Notice that 1 = HCF(2,1) = HCF(21,2) = HCF(23,21) = HCF(44,23) = HCF(243,44) = HCF(287,243) = HCF(530,287) = HCF(817,530) .
