HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 86, 84, 91, 217 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 86, 84, 91, 217 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, 84, 91, 217 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, 84, 91, 217 is 1.
HCF(86, 84, 91, 217) = 1
HCF of 86, 84, 91, 217 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, 84, 91, 217 is 1.
Highest Common Factor of 86,84,91,217 is 1
Step 1: Since 86 > 84, we apply the division lemma to 86 and 84, to get
86 = 84 x 1 + 2
Step 2: Since the reminder 84 ≠ 0, we apply division lemma to 2 and 84, to get
84 = 2 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 86 and 84 is 2
Notice that 2 = HCF(84,2) = HCF(86,84) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 91 > 2, we apply the division lemma to 91 and 2, to get
91 = 2 x 45 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 91 is 1
Notice that 1 = HCF(2,1) = HCF(91,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 217 > 1, we apply the division lemma to 217 and 1, to get
217 = 1 x 217 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 217 is 1
Notice that 1 = HCF(217,1) .
