HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 395, 602, 813 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 395, 602, 813 is 1 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, 602, 813 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, 602, 813 is 1.
HCF(395, 602, 813) = 1
HCF of 395, 602, 813 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, 602, 813 is 1.
Highest Common Factor of 395,602,813 is 1
Step 1: Since 602 > 395, we apply the division lemma to 602 and 395, to get
602 = 395 x 1 + 207
Step 2: Since the reminder 395 ≠ 0, we apply division lemma to 207 and 395, to get
395 = 207 x 1 + 188
Step 3: We consider the new divisor 207 and the new remainder 188, and apply the division lemma to get
207 = 188 x 1 + 19
We consider the new divisor 188 and the new remainder 19,and apply the division lemma to get
188 = 19 x 9 + 17
We consider the new divisor 19 and the new remainder 17,and apply the division lemma to get
19 = 17 x 1 + 2
We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get
17 = 2 x 8 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 395 and 602 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(19,17) = HCF(188,19) = HCF(207,188) = HCF(395,207) = HCF(602,395) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 813 > 1, we apply the division lemma to 813 and 1, to get
813 = 1 x 813 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 813 is 1
Notice that 1 = HCF(813,1) .
