HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 784, 1636, 4982 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 784, 1636, 4982 is 2 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 784, 1636, 4982 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 784, 1636, 4982 is 2.
HCF(784, 1636, 4982) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 784, 1636, 4982 is 2.
Step 1: Since 1636 > 784, we apply the division lemma to 1636 and 784, to get
1636 = 784 x 2 + 68
Step 2: Since the reminder 784 ≠ 0, we apply division lemma to 68 and 784, to get
784 = 68 x 11 + 36
Step 3: We consider the new divisor 68 and the new remainder 36, and apply the division lemma to get
68 = 36 x 1 + 32
We consider the new divisor 36 and the new remainder 32,and apply the division lemma to get
36 = 32 x 1 + 4
We consider the new divisor 32 and the new remainder 4,and apply the division lemma to get
32 = 4 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 784 and 1636 is 4
Notice that 4 = HCF(32,4) = HCF(36,32) = HCF(68,36) = HCF(784,68) = HCF(1636,784) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 4982 > 4, we apply the division lemma to 4982 and 4, to get
4982 = 4 x 1245 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 4982 is 2
Notice that 2 = HCF(4,2) = HCF(4982,4) .
Here are some samples of HCF using Euclid's Algorithm calculations.
