HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 481, 792, 247 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 481, 792, 247 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 481, 792, 247 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 481, 792, 247 is 1.
HCF(481, 792, 247) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 481, 792, 247 is 1.
Step 1: Since 792 > 481, we apply the division lemma to 792 and 481, to get
792 = 481 x 1 + 311
Step 2: Since the reminder 481 ≠ 0, we apply division lemma to 311 and 481, to get
481 = 311 x 1 + 170
Step 3: We consider the new divisor 311 and the new remainder 170, and apply the division lemma to get
311 = 170 x 1 + 141
We consider the new divisor 170 and the new remainder 141,and apply the division lemma to get
170 = 141 x 1 + 29
We consider the new divisor 141 and the new remainder 29,and apply the division lemma to get
141 = 29 x 4 + 25
We consider the new divisor 29 and the new remainder 25,and apply the division lemma to get
29 = 25 x 1 + 4
We consider the new divisor 25 and the new remainder 4,and apply the division lemma to get
25 = 4 x 6 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 481 and 792 is 1
Notice that 1 = HCF(4,1) = HCF(25,4) = HCF(29,25) = HCF(141,29) = HCF(170,141) = HCF(311,170) = HCF(481,311) = HCF(792,481) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 247 > 1, we apply the division lemma to 247 and 1, to get
247 = 1 x 247 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 247 is 1
Notice that 1 = HCF(247,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
