HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 204, 765, 181 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 204, 765, 181 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 204, 765, 181 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 204, 765, 181 is 1.
HCF(204, 765, 181) = 1
HCF of 204, 765, 181 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 204, 765, 181 is 1.
Highest Common Factor of 204,765,181 is 1
Step 1: Since 765 > 204, we apply the division lemma to 765 and 204, to get
765 = 204 x 3 + 153
Step 2: Since the reminder 204 ≠ 0, we apply division lemma to 153 and 204, to get
204 = 153 x 1 + 51
Step 3: We consider the new divisor 153 and the new remainder 51, and apply the division lemma to get
153 = 51 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 51, the HCF of 204 and 765 is 51
Notice that 51 = HCF(153,51) = HCF(204,153) = HCF(765,204) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 181 > 51, we apply the division lemma to 181 and 51, to get
181 = 51 x 3 + 28
Step 2: Since the reminder 51 ≠ 0, we apply division lemma to 28 and 51, to get
51 = 28 x 1 + 23
Step 3: We consider the new divisor 28 and the new remainder 23, and apply the division lemma to get
28 = 23 x 1 + 5
We consider the new divisor 23 and the new remainder 5,and apply the division lemma to get
23 = 5 x 4 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
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 51 and 181 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(23,5) = HCF(28,23) = HCF(51,28) = HCF(181,51) .
