HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 636, 395, 323 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 636, 395, 323 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 636, 395, 323 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 636, 395, 323 is 1.
HCF(636, 395, 323) = 1
HCF of 636, 395, 323 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 636, 395, 323 is 1.
Highest Common Factor of 636,395,323 is 1
Step 1: Since 636 > 395, we apply the division lemma to 636 and 395, to get
636 = 395 x 1 + 241
Step 2: Since the reminder 395 ≠ 0, we apply division lemma to 241 and 395, to get
395 = 241 x 1 + 154
Step 3: We consider the new divisor 241 and the new remainder 154, and apply the division lemma to get
241 = 154 x 1 + 87
We consider the new divisor 154 and the new remainder 87,and apply the division lemma to get
154 = 87 x 1 + 67
We consider the new divisor 87 and the new remainder 67,and apply the division lemma to get
87 = 67 x 1 + 20
We consider the new divisor 67 and the new remainder 20,and apply the division lemma to get
67 = 20 x 3 + 7
We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get
20 = 7 x 2 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 636 and 395 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(67,20) = HCF(87,67) = HCF(154,87) = HCF(241,154) = HCF(395,241) = HCF(636,395) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 323 > 1, we apply the division lemma to 323 and 1, to get
323 = 1 x 323 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 323 is 1
Notice that 1 = HCF(323,1) .
