HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 859, 241, 81 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 859, 241, 81 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 859, 241, 81 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 859, 241, 81 is 1.
HCF(859, 241, 81) = 1
HCF of 859, 241, 81 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 859, 241, 81 is 1.
Highest Common Factor of 859,241,81 is 1
Step 1: Since 859 > 241, we apply the division lemma to 859 and 241, to get
859 = 241 x 3 + 136
Step 2: Since the reminder 241 ≠ 0, we apply division lemma to 136 and 241, to get
241 = 136 x 1 + 105
Step 3: We consider the new divisor 136 and the new remainder 105, and apply the division lemma to get
136 = 105 x 1 + 31
We consider the new divisor 105 and the new remainder 31,and apply the division lemma to get
105 = 31 x 3 + 12
We consider the new divisor 31 and the new remainder 12,and apply the division lemma to get
31 = 12 x 2 + 7
We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get
12 = 7 x 1 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 859 and 241 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(31,12) = HCF(105,31) = HCF(136,105) = HCF(241,136) = HCF(859,241) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 81 > 1, we apply the division lemma to 81 and 1, to get
81 = 1 x 81 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 81 is 1
Notice that 1 = HCF(81,1) .
