HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1458, 5028, 78981 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 1458, 5028, 78981 is 3 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 1458, 5028, 78981 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 1458, 5028, 78981 is 3.
HCF(1458, 5028, 78981) = 3
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1458, 5028, 78981 is 3.
Step 1: Since 5028 > 1458, we apply the division lemma to 5028 and 1458, to get
5028 = 1458 x 3 + 654
Step 2: Since the reminder 1458 ≠ 0, we apply division lemma to 654 and 1458, to get
1458 = 654 x 2 + 150
Step 3: We consider the new divisor 654 and the new remainder 150, and apply the division lemma to get
654 = 150 x 4 + 54
We consider the new divisor 150 and the new remainder 54,and apply the division lemma to get
150 = 54 x 2 + 42
We consider the new divisor 54 and the new remainder 42,and apply the division lemma to get
54 = 42 x 1 + 12
We consider the new divisor 42 and the new remainder 12,and apply the division lemma to get
42 = 12 x 3 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 1458 and 5028 is 6
Notice that 6 = HCF(12,6) = HCF(42,12) = HCF(54,42) = HCF(150,54) = HCF(654,150) = HCF(1458,654) = HCF(5028,1458) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 78981 > 6, we apply the division lemma to 78981 and 6, to get
78981 = 6 x 13163 + 3
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 3 and 6, to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 6 and 78981 is 3
Notice that 3 = HCF(6,3) = HCF(78981,6) .
Here are some samples of HCF using Euclid's Algorithm calculations.
