HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 8219, 4923, 76729 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 8219, 4923, 76729 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 8219, 4923, 76729 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 8219, 4923, 76729 is 1.
HCF(8219, 4923, 76729) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 8219, 4923, 76729 is 1.
Step 1: Since 8219 > 4923, we apply the division lemma to 8219 and 4923, to get
8219 = 4923 x 1 + 3296
Step 2: Since the reminder 4923 ≠ 0, we apply division lemma to 3296 and 4923, to get
4923 = 3296 x 1 + 1627
Step 3: We consider the new divisor 3296 and the new remainder 1627, and apply the division lemma to get
3296 = 1627 x 2 + 42
We consider the new divisor 1627 and the new remainder 42,and apply the division lemma to get
1627 = 42 x 38 + 31
We consider the new divisor 42 and the new remainder 31,and apply the division lemma to get
42 = 31 x 1 + 11
We consider the new divisor 31 and the new remainder 11,and apply the division lemma to get
31 = 11 x 2 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 8219 and 4923 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(31,11) = HCF(42,31) = HCF(1627,42) = HCF(3296,1627) = HCF(4923,3296) = HCF(8219,4923) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 76729 > 1, we apply the division lemma to 76729 and 1, to get
76729 = 1 x 76729 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 76729 is 1
Notice that 1 = HCF(76729,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
