HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 817, 6966, 5290 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 817, 6966, 5290 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, 6966, 5290 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, 6966, 5290 is 1.
HCF(817, 6966, 5290) = 1
HCF of 817, 6966, 5290 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, 6966, 5290 is 1.
Highest Common Factor of 817,6966,5290 is 1
Step 1: Since 6966 > 817, we apply the division lemma to 6966 and 817, to get
6966 = 817 x 8 + 430
Step 2: Since the reminder 817 ≠ 0, we apply division lemma to 430 and 817, to get
817 = 430 x 1 + 387
Step 3: We consider the new divisor 430 and the new remainder 387, and apply the division lemma to get
430 = 387 x 1 + 43
We consider the new divisor 387 and the new remainder 43, and apply the division lemma to get
387 = 43 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 43, the HCF of 817 and 6966 is 43
Notice that 43 = HCF(387,43) = HCF(430,387) = HCF(817,430) = HCF(6966,817) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 5290 > 43, we apply the division lemma to 5290 and 43, to get
5290 = 43 x 123 + 1
Step 2: Since the reminder 43 ≠ 0, we apply division lemma to 1 and 43, to get
43 = 1 x 43 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 43 and 5290 is 1
Notice that 1 = HCF(43,1) = HCF(5290,43) .
