HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 201, 132, 818 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 201, 132, 818 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 201, 132, 818 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 201, 132, 818 is 1.
HCF(201, 132, 818) = 1
HCF of 201, 132, 818 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 201, 132, 818 is 1.
Highest Common Factor of 201,132,818 is 1
Step 1: Since 201 > 132, we apply the division lemma to 201 and 132, to get
201 = 132 x 1 + 69
Step 2: Since the reminder 132 ≠ 0, we apply division lemma to 69 and 132, to get
132 = 69 x 1 + 63
Step 3: We consider the new divisor 69 and the new remainder 63, and apply the division lemma to get
69 = 63 x 1 + 6
We consider the new divisor 63 and the new remainder 6,and apply the division lemma to get
63 = 6 x 10 + 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 201 and 132 is 3
Notice that 3 = HCF(6,3) = HCF(63,6) = HCF(69,63) = HCF(132,69) = HCF(201,132) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 818 > 3, we apply the division lemma to 818 and 3, to get
818 = 3 x 272 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 818 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(818,3) .
