HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 515, 205, 95 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 515, 205, 95 is 5 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 515, 205, 95 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 515, 205, 95 is 5.
HCF(515, 205, 95) = 5
HCF of 515, 205, 95 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 515, 205, 95 is 5.
Highest Common Factor of 515,205,95 is 5
Step 1: Since 515 > 205, we apply the division lemma to 515 and 205, to get
515 = 205 x 2 + 105
Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 105 and 205, to get
205 = 105 x 1 + 100
Step 3: We consider the new divisor 105 and the new remainder 100, and apply the division lemma to get
105 = 100 x 1 + 5
We consider the new divisor 100 and the new remainder 5, and apply the division lemma to get
100 = 5 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 515 and 205 is 5
Notice that 5 = HCF(100,5) = HCF(105,100) = HCF(205,105) = HCF(515,205) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 95 > 5, we apply the division lemma to 95 and 5, to get
95 = 5 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 95 is 5
Notice that 5 = HCF(95,5) .
