HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 789, 452, 406 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 789, 452, 406 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, 452, 406 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, 452, 406 is 1.
HCF(789, 452, 406) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 789, 452, 406 is 1.
Step 1: Since 789 > 452, we apply the division lemma to 789 and 452, to get
789 = 452 x 1 + 337
Step 2: Since the reminder 452 ≠ 0, we apply division lemma to 337 and 452, to get
452 = 337 x 1 + 115
Step 3: We consider the new divisor 337 and the new remainder 115, and apply the division lemma to get
337 = 115 x 2 + 107
We consider the new divisor 115 and the new remainder 107,and apply the division lemma to get
115 = 107 x 1 + 8
We consider the new divisor 107 and the new remainder 8,and apply the division lemma to get
107 = 8 x 13 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 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 789 and 452 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(107,8) = HCF(115,107) = HCF(337,115) = HCF(452,337) = HCF(789,452) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 406 > 1, we apply the division lemma to 406 and 1, to get
406 = 1 x 406 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 406 is 1
Notice that 1 = HCF(406,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
