HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 462, 261, 993 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 462, 261, 993 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 462, 261, 993 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 462, 261, 993 is 3.
HCF(462, 261, 993) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 462, 261, 993 is 3.
Step 1: Since 462 > 261, we apply the division lemma to 462 and 261, to get
462 = 261 x 1 + 201
Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 201 and 261, to get
261 = 201 x 1 + 60
Step 3: We consider the new divisor 201 and the new remainder 60, and apply the division lemma to get
201 = 60 x 3 + 21
We consider the new divisor 60 and the new remainder 21,and apply the division lemma to get
60 = 21 x 2 + 18
We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 462 and 261 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(60,21) = HCF(201,60) = HCF(261,201) = HCF(462,261) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 993 > 3, we apply the division lemma to 993 and 3, to get
993 = 3 x 331 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 993 is 3
Notice that 3 = HCF(993,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
