HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 284, 984, 439 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 284, 984, 439 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 284, 984, 439 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 284, 984, 439 is 1.
HCF(284, 984, 439) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 284, 984, 439 is 1.
Step 1: Since 984 > 284, we apply the division lemma to 984 and 284, to get
984 = 284 x 3 + 132
Step 2: Since the reminder 284 ≠ 0, we apply division lemma to 132 and 284, to get
284 = 132 x 2 + 20
Step 3: We consider the new divisor 132 and the new remainder 20, and apply the division lemma to get
132 = 20 x 6 + 12
We consider the new divisor 20 and the new remainder 12,and apply the division lemma to get
20 = 12 x 1 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 284 and 984 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(132,20) = HCF(284,132) = HCF(984,284) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 439 > 4, we apply the division lemma to 439 and 4, to get
439 = 4 x 109 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 439 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(439,4) .
Here are some samples of HCF using Euclid's Algorithm calculations.
