HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 447, 773, 489, 231 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 447, 773, 489, 231 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 447, 773, 489, 231 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 447, 773, 489, 231 is 1.
HCF(447, 773, 489, 231) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 447, 773, 489, 231 is 1.
Step 1: Since 773 > 447, we apply the division lemma to 773 and 447, to get
773 = 447 x 1 + 326
Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 326 and 447, to get
447 = 326 x 1 + 121
Step 3: We consider the new divisor 326 and the new remainder 121, and apply the division lemma to get
326 = 121 x 2 + 84
We consider the new divisor 121 and the new remainder 84,and apply the division lemma to get
121 = 84 x 1 + 37
We consider the new divisor 84 and the new remainder 37,and apply the division lemma to get
84 = 37 x 2 + 10
We consider the new divisor 37 and the new remainder 10,and apply the division lemma to get
37 = 10 x 3 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 447 and 773 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(37,10) = HCF(84,37) = HCF(121,84) = HCF(326,121) = HCF(447,326) = HCF(773,447) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 489 > 1, we apply the division lemma to 489 and 1, to get
489 = 1 x 489 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 489 is 1
Notice that 1 = HCF(489,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 231 > 1, we apply the division lemma to 231 and 1, to get
231 = 1 x 231 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 231 is 1
Notice that 1 = HCF(231,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
