HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 479, 790, 282 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 479, 790, 282 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 479, 790, 282 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 479, 790, 282 is 1.
HCF(479, 790, 282) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 479, 790, 282 is 1.
Step 1: Since 790 > 479, we apply the division lemma to 790 and 479, to get
790 = 479 x 1 + 311
Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 311 and 479, to get
479 = 311 x 1 + 168
Step 3: We consider the new divisor 311 and the new remainder 168, and apply the division lemma to get
311 = 168 x 1 + 143
We consider the new divisor 168 and the new remainder 143,and apply the division lemma to get
168 = 143 x 1 + 25
We consider the new divisor 143 and the new remainder 25,and apply the division lemma to get
143 = 25 x 5 + 18
We consider the new divisor 25 and the new remainder 18,and apply the division lemma to get
25 = 18 x 1 + 7
We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get
18 = 7 x 2 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
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 479 and 790 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(25,18) = HCF(143,25) = HCF(168,143) = HCF(311,168) = HCF(479,311) = HCF(790,479) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 282 > 1, we apply the division lemma to 282 and 1, to get
282 = 1 x 282 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 282 is 1
Notice that 1 = HCF(282,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
