HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 174, 973, 819 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 174, 973, 819 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 174, 973, 819 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 174, 973, 819 is 1.
HCF(174, 973, 819) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 174, 973, 819 is 1.
Step 1: Since 973 > 174, we apply the division lemma to 973 and 174, to get
973 = 174 x 5 + 103
Step 2: Since the reminder 174 ≠ 0, we apply division lemma to 103 and 174, to get
174 = 103 x 1 + 71
Step 3: We consider the new divisor 103 and the new remainder 71, and apply the division lemma to get
103 = 71 x 1 + 32
We consider the new divisor 71 and the new remainder 32,and apply the division lemma to get
71 = 32 x 2 + 7
We consider the new divisor 32 and the new remainder 7,and apply the division lemma to get
32 = 7 x 4 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 174 and 973 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(32,7) = HCF(71,32) = HCF(103,71) = HCF(174,103) = HCF(973,174) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 819 > 1, we apply the division lemma to 819 and 1, to get
819 = 1 x 819 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 819 is 1
Notice that 1 = HCF(819,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
