HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 768, 384, 201 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 768, 384, 201 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 768, 384, 201 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 768, 384, 201 is 3.
HCF(768, 384, 201) = 3
HCF of 768, 384, 201 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 768, 384, 201 is 3.
Highest Common Factor of 768,384,201 is 3
Step 1: Since 768 > 384, we apply the division lemma to 768 and 384, to get
768 = 384 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 384, the HCF of 768 and 384 is 384
Notice that 384 = HCF(768,384) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 384 > 201, we apply the division lemma to 384 and 201, to get
384 = 201 x 1 + 183
Step 2: Since the reminder 201 ≠ 0, we apply division lemma to 183 and 201, to get
201 = 183 x 1 + 18
Step 3: We consider the new divisor 183 and the new remainder 18, and apply the division lemma to get
183 = 18 x 10 + 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 384 and 201 is 3
Notice that 3 = HCF(18,3) = HCF(183,18) = HCF(201,183) = HCF(384,201) .
