HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7854, 7779, 14636 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7854, 7779, 14636 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 7854, 7779, 14636 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 7854, 7779, 14636 is 1.
HCF(7854, 7779, 14636) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7854, 7779, 14636 is 1.
Step 1: Since 7854 > 7779, we apply the division lemma to 7854 and 7779, to get
7854 = 7779 x 1 + 75
Step 2: Since the reminder 7779 ≠ 0, we apply division lemma to 75 and 7779, to get
7779 = 75 x 103 + 54
Step 3: We consider the new divisor 75 and the new remainder 54, and apply the division lemma to get
75 = 54 x 1 + 21
We consider the new divisor 54 and the new remainder 21,and apply the division lemma to get
54 = 21 x 2 + 12
We consider the new divisor 21 and the new remainder 12,and apply the division lemma to get
21 = 12 x 1 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 7854 and 7779 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(21,12) = HCF(54,21) = HCF(75,54) = HCF(7779,75) = HCF(7854,7779) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 14636 > 3, we apply the division lemma to 14636 and 3, to get
14636 = 3 x 4878 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 14636 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14636,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
