HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 789, 201, 14 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 789, 201, 14 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 789, 201, 14 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 789, 201, 14 is 1.
HCF(789, 201, 14) = 1
HCF of 789, 201, 14 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 789, 201, 14 is 1.
Highest Common Factor of 789,201,14 is 1
Step 1: Since 789 > 201, we apply the division lemma to 789 and 201, to get
789 = 201 x 3 + 186
Step 2: Since the reminder 201 ≠ 0, we apply division lemma to 186 and 201, to get
201 = 186 x 1 + 15
Step 3: We consider the new divisor 186 and the new remainder 15, and apply the division lemma to get
186 = 15 x 12 + 6
We consider the new divisor 15 and the new remainder 6,and apply the division lemma to get
15 = 6 x 2 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 789 and 201 is 3
Notice that 3 = HCF(6,3) = HCF(15,6) = HCF(186,15) = HCF(201,186) = HCF(789,201) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 14 > 3, we apply the division lemma to 14 and 3, to get
14 = 3 x 4 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 14 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) .
