HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 933, 201, 814 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 933, 201, 814 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 933, 201, 814 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 933, 201, 814 is 1.
HCF(933, 201, 814) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 933, 201, 814 is 1.
Step 1: Since 933 > 201, we apply the division lemma to 933 and 201, to get
933 = 201 x 4 + 129
Step 2: Since the reminder 201 ≠ 0, we apply division lemma to 129 and 201, to get
201 = 129 x 1 + 72
Step 3: We consider the new divisor 129 and the new remainder 72, and apply the division lemma to get
129 = 72 x 1 + 57
We consider the new divisor 72 and the new remainder 57,and apply the division lemma to get
72 = 57 x 1 + 15
We consider the new divisor 57 and the new remainder 15,and apply the division lemma to get
57 = 15 x 3 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 933 and 201 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(57,15) = HCF(72,57) = HCF(129,72) = HCF(201,129) = HCF(933,201) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 814 > 3, we apply the division lemma to 814 and 3, to get
814 = 3 x 271 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 814 is 1
Notice that 1 = HCF(3,1) = HCF(814,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
