HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 581, 781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 581, 781 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 581, 781 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 581, 781 is 1.
HCF(581, 781) = 1
HCF of 581, 781 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 581, 781 is 1.
Highest Common Factor of 581,781 is 1
Step 1: Since 781 > 581, we apply the division lemma to 781 and 581, to get
781 = 581 x 1 + 200
Step 2: Since the reminder 581 ≠ 0, we apply division lemma to 200 and 581, to get
581 = 200 x 2 + 181
Step 3: We consider the new divisor 200 and the new remainder 181, and apply the division lemma to get
200 = 181 x 1 + 19
We consider the new divisor 181 and the new remainder 19,and apply the division lemma to get
181 = 19 x 9 + 10
We consider the new divisor 19 and the new remainder 10,and apply the division lemma to get
19 = 10 x 1 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 581 and 781 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(19,10) = HCF(181,19) = HCF(200,181) = HCF(581,200) = HCF(781,581) .
