HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 86, 43, 91, 546 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 86, 43, 91, 546 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, 43, 91, 546 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, 43, 91, 546 is 1.
HCF(86, 43, 91, 546) = 1
HCF of 86, 43, 91, 546 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, 43, 91, 546 is 1.
Highest Common Factor of 86,43,91,546 is 1
Step 1: Since 86 > 43, we apply the division lemma to 86 and 43, to get
86 = 43 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 43, the HCF of 86 and 43 is 43
Notice that 43 = HCF(86,43) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 91 > 43, we apply the division lemma to 91 and 43, to get
91 = 43 x 2 + 5
Step 2: Since the reminder 43 ≠ 0, we apply division lemma to 5 and 43, to get
43 = 5 x 8 + 3
Step 3: We consider the new divisor 5 and the new remainder 3, and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 43 and 91 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(43,5) = HCF(91,43) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 546 > 1, we apply the division lemma to 546 and 1, to get
546 = 1 x 546 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 546 is 1
Notice that 1 = HCF(546,1) .
