HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 810, 499, 579 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 810, 499, 579 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 810, 499, 579 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 810, 499, 579 is 1.
HCF(810, 499, 579) = 1
HCF of 810, 499, 579 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 810, 499, 579 is 1.
Highest Common Factor of 810,499,579 is 1
Step 1: Since 810 > 499, we apply the division lemma to 810 and 499, to get
810 = 499 x 1 + 311
Step 2: Since the reminder 499 ≠ 0, we apply division lemma to 311 and 499, to get
499 = 311 x 1 + 188
Step 3: We consider the new divisor 311 and the new remainder 188, and apply the division lemma to get
311 = 188 x 1 + 123
We consider the new divisor 188 and the new remainder 123,and apply the division lemma to get
188 = 123 x 1 + 65
We consider the new divisor 123 and the new remainder 65,and apply the division lemma to get
123 = 65 x 1 + 58
We consider the new divisor 65 and the new remainder 58,and apply the division lemma to get
65 = 58 x 1 + 7
We consider the new divisor 58 and the new remainder 7,and apply the division lemma to get
58 = 7 x 8 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 810 and 499 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(58,7) = HCF(65,58) = HCF(123,65) = HCF(188,123) = HCF(311,188) = HCF(499,311) = HCF(810,499) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 579 > 1, we apply the division lemma to 579 and 1, to get
579 = 1 x 579 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 579 is 1
Notice that 1 = HCF(579,1) .
