HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 819, 301, 881 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 819, 301, 881 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 819, 301, 881 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 819, 301, 881 is 1.
HCF(819, 301, 881) = 1
HCF of 819, 301, 881 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 819, 301, 881 is 1.
Highest Common Factor of 819,301,881 is 1
Step 1: Since 819 > 301, we apply the division lemma to 819 and 301, to get
819 = 301 x 2 + 217
Step 2: Since the reminder 301 ≠ 0, we apply division lemma to 217 and 301, to get
301 = 217 x 1 + 84
Step 3: We consider the new divisor 217 and the new remainder 84, and apply the division lemma to get
217 = 84 x 2 + 49
We consider the new divisor 84 and the new remainder 49,and apply the division lemma to get
84 = 49 x 1 + 35
We consider the new divisor 49 and the new remainder 35,and apply the division lemma to get
49 = 35 x 1 + 14
We consider the new divisor 35 and the new remainder 14,and apply the division lemma to get
35 = 14 x 2 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 819 and 301 is 7
Notice that 7 = HCF(14,7) = HCF(35,14) = HCF(49,35) = HCF(84,49) = HCF(217,84) = HCF(301,217) = HCF(819,301) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 881 > 7, we apply the division lemma to 881 and 7, to get
881 = 7 x 125 + 6
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 6 and 7, to get
7 = 6 x 1 + 1
Step 3: We consider the new divisor 6 and the new remainder 1, and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 881 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(881,7) .
