HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 621, 997, 114 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 621, 997, 114 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 621, 997, 114 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 621, 997, 114 is 1.
HCF(621, 997, 114) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 621, 997, 114 is 1.
Step 1: Since 997 > 621, we apply the division lemma to 997 and 621, to get
997 = 621 x 1 + 376
Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 376 and 621, to get
621 = 376 x 1 + 245
Step 3: We consider the new divisor 376 and the new remainder 245, and apply the division lemma to get
376 = 245 x 1 + 131
We consider the new divisor 245 and the new remainder 131,and apply the division lemma to get
245 = 131 x 1 + 114
We consider the new divisor 131 and the new remainder 114,and apply the division lemma to get
131 = 114 x 1 + 17
We consider the new divisor 114 and the new remainder 17,and apply the division lemma to get
114 = 17 x 6 + 12
We consider the new divisor 17 and the new remainder 12,and apply the division lemma to get
17 = 12 x 1 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 621 and 997 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(17,12) = HCF(114,17) = HCF(131,114) = HCF(245,131) = HCF(376,245) = HCF(621,376) = HCF(997,621) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 114 > 1, we apply the division lemma to 114 and 1, to get
114 = 1 x 114 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 114 is 1
Notice that 1 = HCF(114,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
