HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 205, 581, 912 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 205, 581, 912 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 205, 581, 912 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 205, 581, 912 is 1.
HCF(205, 581, 912) = 1
HCF of 205, 581, 912 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 205, 581, 912 is 1.
Highest Common Factor of 205,581,912 is 1
Step 1: Since 581 > 205, we apply the division lemma to 581 and 205, to get
581 = 205 x 2 + 171
Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 171 and 205, to get
205 = 171 x 1 + 34
Step 3: We consider the new divisor 171 and the new remainder 34, and apply the division lemma to get
171 = 34 x 5 + 1
We consider the new divisor 34 and the new remainder 1, and apply the division lemma to get
34 = 1 x 34 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 205 and 581 is 1
Notice that 1 = HCF(34,1) = HCF(171,34) = HCF(205,171) = HCF(581,205) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 912 > 1, we apply the division lemma to 912 and 1, to get
912 = 1 x 912 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 912 is 1
Notice that 1 = HCF(912,1) .
