HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 204, 87 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 204, 87 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 204, 87 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, 87 is 3.
HCF(204, 87) = 3
HCF of 204, 87 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, 87 is 3.
Highest Common Factor of 204,87 is 3
Step 1: Since 204 > 87, we apply the division lemma to 204 and 87, to get
204 = 87 x 2 + 30
Step 2: Since the reminder 87 ≠ 0, we apply division lemma to 30 and 87, to get
87 = 30 x 2 + 27
Step 3: We consider the new divisor 30 and the new remainder 27, and apply the division lemma to get
30 = 27 x 1 + 3
We consider the new divisor 27 and the new remainder 3, and apply the division lemma to get
27 = 3 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 204 and 87 is 3
Notice that 3 = HCF(27,3) = HCF(30,27) = HCF(87,30) = HCF(204,87) .
