HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 997, 368, 235 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 997, 368, 235 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 997, 368, 235 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 997, 368, 235 is 1.
HCF(997, 368, 235) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 997, 368, 235 is 1.
Step 1: Since 997 > 368, we apply the division lemma to 997 and 368, to get
997 = 368 x 2 + 261
Step 2: Since the reminder 368 ≠ 0, we apply division lemma to 261 and 368, to get
368 = 261 x 1 + 107
Step 3: We consider the new divisor 261 and the new remainder 107, and apply the division lemma to get
261 = 107 x 2 + 47
We consider the new divisor 107 and the new remainder 47,and apply the division lemma to get
107 = 47 x 2 + 13
We consider the new divisor 47 and the new remainder 13,and apply the division lemma to get
47 = 13 x 3 + 8
We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get
13 = 8 x 1 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 997 and 368 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(47,13) = HCF(107,47) = HCF(261,107) = HCF(368,261) = HCF(997,368) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 235 > 1, we apply the division lemma to 235 and 1, to get
235 = 1 x 235 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 235 is 1
Notice that 1 = HCF(235,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
