HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 459, 785, 587 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 459, 785, 587 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 459, 785, 587 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 459, 785, 587 is 1.
HCF(459, 785, 587) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 459, 785, 587 is 1.
Step 1: Since 785 > 459, we apply the division lemma to 785 and 459, to get
785 = 459 x 1 + 326
Step 2: Since the reminder 459 ≠ 0, we apply division lemma to 326 and 459, to get
459 = 326 x 1 + 133
Step 3: We consider the new divisor 326 and the new remainder 133, and apply the division lemma to get
326 = 133 x 2 + 60
We consider the new divisor 133 and the new remainder 60,and apply the division lemma to get
133 = 60 x 2 + 13
We consider the new divisor 60 and the new remainder 13,and apply the division lemma to get
60 = 13 x 4 + 8
We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get
13 = 8 x 1 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 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 459 and 785 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(60,13) = HCF(133,60) = HCF(326,133) = HCF(459,326) = HCF(785,459) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 587 > 1, we apply the division lemma to 587 and 1, to get
587 = 1 x 587 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 587 is 1
Notice that 1 = HCF(587,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
