HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 857, 311, 181 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 857, 311, 181 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 857, 311, 181 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 857, 311, 181 is 1.
HCF(857, 311, 181) = 1
HCF of 857, 311, 181 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 857, 311, 181 is 1.
Highest Common Factor of 857,311,181 is 1
Step 1: Since 857 > 311, we apply the division lemma to 857 and 311, to get
857 = 311 x 2 + 235
Step 2: Since the reminder 311 ≠ 0, we apply division lemma to 235 and 311, to get
311 = 235 x 1 + 76
Step 3: We consider the new divisor 235 and the new remainder 76, and apply the division lemma to get
235 = 76 x 3 + 7
We consider the new divisor 76 and the new remainder 7,and apply the division lemma to get
76 = 7 x 10 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
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 857 and 311 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(76,7) = HCF(235,76) = HCF(311,235) = HCF(857,311) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 181 > 1, we apply the division lemma to 181 and 1, to get
181 = 1 x 181 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 181 is 1
Notice that 1 = HCF(181,1) .
