HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 86, 67, 861 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 86, 67, 861 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 86, 67, 861 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 86, 67, 861 is 1.
HCF(86, 67, 861) = 1
HCF of 86, 67, 861 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 86, 67, 861 is 1.
Highest Common Factor of 86,67,861 is 1
Step 1: Since 86 > 67, we apply the division lemma to 86 and 67, to get
86 = 67 x 1 + 19
Step 2: Since the reminder 67 ≠ 0, we apply division lemma to 19 and 67, to get
67 = 19 x 3 + 10
Step 3: We consider the new divisor 19 and the new remainder 10, and apply the division lemma to get
19 = 10 x 1 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 86 and 67 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(19,10) = HCF(67,19) = HCF(86,67) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 861 > 1, we apply the division lemma to 861 and 1, to get
861 = 1 x 861 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 861 is 1
Notice that 1 = HCF(861,1) .
