HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 805, 306, 581 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 805, 306, 581 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 805, 306, 581 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 805, 306, 581 is 1.
HCF(805, 306, 581) = 1
HCF of 805, 306, 581 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 805, 306, 581 is 1.
Highest Common Factor of 805,306,581 is 1
Step 1: Since 805 > 306, we apply the division lemma to 805 and 306, to get
805 = 306 x 2 + 193
Step 2: Since the reminder 306 ≠ 0, we apply division lemma to 193 and 306, to get
306 = 193 x 1 + 113
Step 3: We consider the new divisor 193 and the new remainder 113, and apply the division lemma to get
193 = 113 x 1 + 80
We consider the new divisor 113 and the new remainder 80,and apply the division lemma to get
113 = 80 x 1 + 33
We consider the new divisor 80 and the new remainder 33,and apply the division lemma to get
80 = 33 x 2 + 14
We consider the new divisor 33 and the new remainder 14,and apply the division lemma to get
33 = 14 x 2 + 5
We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get
14 = 5 x 2 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
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 805 and 306 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(33,14) = HCF(80,33) = HCF(113,80) = HCF(193,113) = HCF(306,193) = HCF(805,306) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 581 > 1, we apply the division lemma to 581 and 1, to get
581 = 1 x 581 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 581 is 1
Notice that 1 = HCF(581,1) .
