HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 395, 930 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 395, 930 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, 930 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, 930 is 5.
HCF(395, 930) = 5
HCF of 395, 930 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, 930 is 5.
Highest Common Factor of 395,930 is 5
Step 1: Since 930 > 395, we apply the division lemma to 930 and 395, to get
930 = 395 x 2 + 140
Step 2: Since the reminder 395 ≠ 0, we apply division lemma to 140 and 395, to get
395 = 140 x 2 + 115
Step 3: We consider the new divisor 140 and the new remainder 115, and apply the division lemma to get
140 = 115 x 1 + 25
We consider the new divisor 115 and the new remainder 25,and apply the division lemma to get
115 = 25 x 4 + 15
We consider the new divisor 25 and the new remainder 15,and apply the division lemma to get
25 = 15 x 1 + 10
We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get
15 = 10 x 1 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 395 and 930 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(25,15) = HCF(115,25) = HCF(140,115) = HCF(395,140) = HCF(930,395) .
