HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 479, 779, 651 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 479, 779, 651 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, 779, 651 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, 779, 651 is 1.
HCF(479, 779, 651) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 479, 779, 651 is 1.
Step 1: Since 779 > 479, we apply the division lemma to 779 and 479, to get
779 = 479 x 1 + 300
Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 300 and 479, to get
479 = 300 x 1 + 179
Step 3: We consider the new divisor 300 and the new remainder 179, and apply the division lemma to get
300 = 179 x 1 + 121
We consider the new divisor 179 and the new remainder 121,and apply the division lemma to get
179 = 121 x 1 + 58
We consider the new divisor 121 and the new remainder 58,and apply the division lemma to get
121 = 58 x 2 + 5
We consider the new divisor 58 and the new remainder 5,and apply the division lemma to get
58 = 5 x 11 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 479 and 779 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(58,5) = HCF(121,58) = HCF(179,121) = HCF(300,179) = HCF(479,300) = HCF(779,479) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 651 > 1, we apply the division lemma to 651 and 1, to get
651 = 1 x 651 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 651 is 1
Notice that 1 = HCF(651,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
