HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 581, 901 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 581, 901 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, 901 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, 901 is 1.
HCF(581, 901) = 1
HCF of 581, 901 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, 901 is 1.
Highest Common Factor of 581,901 is 1
Step 1: Since 901 > 581, we apply the division lemma to 901 and 581, to get
901 = 581 x 1 + 320
Step 2: Since the reminder 581 ≠ 0, we apply division lemma to 320 and 581, to get
581 = 320 x 1 + 261
Step 3: We consider the new divisor 320 and the new remainder 261, and apply the division lemma to get
320 = 261 x 1 + 59
We consider the new divisor 261 and the new remainder 59,and apply the division lemma to get
261 = 59 x 4 + 25
We consider the new divisor 59 and the new remainder 25,and apply the division lemma to get
59 = 25 x 2 + 9
We consider the new divisor 25 and the new remainder 9,and apply the division lemma to get
25 = 9 x 2 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 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 581 and 901 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(25,9) = HCF(59,25) = HCF(261,59) = HCF(320,261) = HCF(581,320) = HCF(901,581) .
