HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 789, 554, 227 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 789, 554, 227 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, 554, 227 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, 554, 227 is 1.
HCF(789, 554, 227) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 789, 554, 227 is 1.
Step 1: Since 789 > 554, we apply the division lemma to 789 and 554, to get
789 = 554 x 1 + 235
Step 2: Since the reminder 554 ≠ 0, we apply division lemma to 235 and 554, to get
554 = 235 x 2 + 84
Step 3: We consider the new divisor 235 and the new remainder 84, and apply the division lemma to get
235 = 84 x 2 + 67
We consider the new divisor 84 and the new remainder 67,and apply the division lemma to get
84 = 67 x 1 + 17
We consider the new divisor 67 and the new remainder 17,and apply the division lemma to get
67 = 17 x 3 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 789 and 554 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(67,17) = HCF(84,67) = HCF(235,84) = HCF(554,235) = HCF(789,554) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 227 > 1, we apply the division lemma to 227 and 1, to get
227 = 1 x 227 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 227 is 1
Notice that 1 = HCF(227,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
