HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 385, 87915 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 385, 87915 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 385, 87915 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 385, 87915 is 5.
HCF(385, 87915) = 5
HCF of 385, 87915 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 385, 87915 is 5.
Highest Common Factor of 385,87915 is 5
Step 1: Since 87915 > 385, we apply the division lemma to 87915 and 385, to get
87915 = 385 x 228 + 135
Step 2: Since the reminder 385 ≠ 0, we apply division lemma to 135 and 385, to get
385 = 135 x 2 + 115
Step 3: We consider the new divisor 135 and the new remainder 115, and apply the division lemma to get
135 = 115 x 1 + 20
We consider the new divisor 115 and the new remainder 20,and apply the division lemma to get
115 = 20 x 5 + 15
We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get
20 = 15 x 1 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 385 and 87915 is 5
Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(115,20) = HCF(135,115) = HCF(385,135) = HCF(87915,385) .
