HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 813, 522, 891 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 813, 522, 891 is 3 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 813, 522, 891 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 813, 522, 891 is 3.
HCF(813, 522, 891) = 3
HCF of 813, 522, 891 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 813, 522, 891 is 3.
Highest Common Factor of 813,522,891 is 3
Step 1: Since 813 > 522, we apply the division lemma to 813 and 522, to get
813 = 522 x 1 + 291
Step 2: Since the reminder 522 ≠ 0, we apply division lemma to 291 and 522, to get
522 = 291 x 1 + 231
Step 3: We consider the new divisor 291 and the new remainder 231, and apply the division lemma to get
291 = 231 x 1 + 60
We consider the new divisor 231 and the new remainder 60,and apply the division lemma to get
231 = 60 x 3 + 51
We consider the new divisor 60 and the new remainder 51,and apply the division lemma to get
60 = 51 x 1 + 9
We consider the new divisor 51 and the new remainder 9,and apply the division lemma to get
51 = 9 x 5 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 813 and 522 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(51,9) = HCF(60,51) = HCF(231,60) = HCF(291,231) = HCF(522,291) = HCF(813,522) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 891 > 3, we apply the division lemma to 891 and 3, to get
891 = 3 x 297 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 891 is 3
Notice that 3 = HCF(891,3) .
