HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 480, 425, 819 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 480, 425, 819 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 480, 425, 819 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 480, 425, 819 is 1.
HCF(480, 425, 819) = 1
HCF of 480, 425, 819 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 480, 425, 819 is 1.
Highest Common Factor of 480,425,819 is 1
Step 1: Since 480 > 425, we apply the division lemma to 480 and 425, to get
480 = 425 x 1 + 55
Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 55 and 425, to get
425 = 55 x 7 + 40
Step 3: We consider the new divisor 55 and the new remainder 40, and apply the division lemma to get
55 = 40 x 1 + 15
We consider the new divisor 40 and the new remainder 15,and apply the division lemma to get
40 = 15 x 2 + 10
We consider the new divisor 15 and the new remainder 10,and apply the division lemma to get
15 = 10 x 1 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 480 and 425 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(40,15) = HCF(55,40) = HCF(425,55) = HCF(480,425) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 819 > 5, we apply the division lemma to 819 and 5, to get
819 = 5 x 163 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 819 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(819,5) .
