HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 395, 5415 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 395, 5415 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 395, 5415 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 395, 5415 is 5.
HCF(395, 5415) = 5
HCF of 395, 5415 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 395, 5415 is 5.
Highest Common Factor of 395,5415 is 5
Step 1: Since 5415 > 395, we apply the division lemma to 5415 and 395, to get
5415 = 395 x 13 + 280
Step 2: Since the reminder 395 ≠ 0, we apply division lemma to 280 and 395, to get
395 = 280 x 1 + 115
Step 3: We consider the new divisor 280 and the new remainder 115, and apply the division lemma to get
280 = 115 x 2 + 50
We consider the new divisor 115 and the new remainder 50,and apply the division lemma to get
115 = 50 x 2 + 15
We consider the new divisor 50 and the new remainder 15,and apply the division lemma to get
50 = 15 x 3 + 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 395 and 5415 is 5
Notice that 5 = HCF(15,5) = HCF(50,15) = HCF(115,50) = HCF(280,115) = HCF(395,280) = HCF(5415,395) .
