HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 419, 293, 769 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 419, 293, 769 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 419, 293, 769 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 419, 293, 769 is 1.
HCF(419, 293, 769) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 419, 293, 769 is 1.
Step 1: Since 419 > 293, we apply the division lemma to 419 and 293, to get
419 = 293 x 1 + 126
Step 2: Since the reminder 293 ≠ 0, we apply division lemma to 126 and 293, to get
293 = 126 x 2 + 41
Step 3: We consider the new divisor 126 and the new remainder 41, and apply the division lemma to get
126 = 41 x 3 + 3
We consider the new divisor 41 and the new remainder 3,and apply the division lemma to get
41 = 3 x 13 + 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 419 and 293 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(41,3) = HCF(126,41) = HCF(293,126) = HCF(419,293) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 769 > 1, we apply the division lemma to 769 and 1, to get
769 = 1 x 769 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 769 is 1
Notice that 1 = HCF(769,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
