HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7496, 4109, 78964 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7496, 4109, 78964 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 7496, 4109, 78964 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 7496, 4109, 78964 is 1.
HCF(7496, 4109, 78964) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7496, 4109, 78964 is 1.
Step 1: Since 7496 > 4109, we apply the division lemma to 7496 and 4109, to get
7496 = 4109 x 1 + 3387
Step 2: Since the reminder 4109 ≠ 0, we apply division lemma to 3387 and 4109, to get
4109 = 3387 x 1 + 722
Step 3: We consider the new divisor 3387 and the new remainder 722, and apply the division lemma to get
3387 = 722 x 4 + 499
We consider the new divisor 722 and the new remainder 499,and apply the division lemma to get
722 = 499 x 1 + 223
We consider the new divisor 499 and the new remainder 223,and apply the division lemma to get
499 = 223 x 2 + 53
We consider the new divisor 223 and the new remainder 53,and apply the division lemma to get
223 = 53 x 4 + 11
We consider the new divisor 53 and the new remainder 11,and apply the division lemma to get
53 = 11 x 4 + 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 7496 and 4109 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(53,11) = HCF(223,53) = HCF(499,223) = HCF(722,499) = HCF(3387,722) = HCF(4109,3387) = HCF(7496,4109) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 78964 > 1, we apply the division lemma to 78964 and 1, to get
78964 = 1 x 78964 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 78964 is 1
Notice that 1 = HCF(78964,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
