HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 173, 789, 396 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 173, 789, 396 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 173, 789, 396 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 173, 789, 396 is 1.
HCF(173, 789, 396) = 1
HCF of 173, 789, 396 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 173, 789, 396 is 1.
Highest Common Factor of 173,789,396 is 1
Step 1: Since 789 > 173, we apply the division lemma to 789 and 173, to get
789 = 173 x 4 + 97
Step 2: Since the reminder 173 ≠ 0, we apply division lemma to 97 and 173, to get
173 = 97 x 1 + 76
Step 3: We consider the new divisor 97 and the new remainder 76, and apply the division lemma to get
97 = 76 x 1 + 21
We consider the new divisor 76 and the new remainder 21,and apply the division lemma to get
76 = 21 x 3 + 13
We consider the new divisor 21 and the new remainder 13,and apply the division lemma to get
21 = 13 x 1 + 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 173 and 789 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(76,21) = HCF(97,76) = HCF(173,97) = HCF(789,173) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 396 > 1, we apply the division lemma to 396 and 1, to get
396 = 1 x 396 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 396 is 1
Notice that 1 = HCF(396,1) .
