HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 813, 2188 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 813, 2188 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 813, 2188 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, 2188 is 1.
HCF(813, 2188) = 1
HCF of 813, 2188 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, 2188 is 1.
Highest Common Factor of 813,2188 is 1
Step 1: Since 2188 > 813, we apply the division lemma to 2188 and 813, to get
2188 = 813 x 2 + 562
Step 2: Since the reminder 813 ≠ 0, we apply division lemma to 562 and 813, to get
813 = 562 x 1 + 251
Step 3: We consider the new divisor 562 and the new remainder 251, and apply the division lemma to get
562 = 251 x 2 + 60
We consider the new divisor 251 and the new remainder 60,and apply the division lemma to get
251 = 60 x 4 + 11
We consider the new divisor 60 and the new remainder 11,and apply the division lemma to get
60 = 11 x 5 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 813 and 2188 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(60,11) = HCF(251,60) = HCF(562,251) = HCF(813,562) = HCF(2188,813) .
