HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 48, 81, 86 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 48, 81, 86 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 48, 81, 86 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 48, 81, 86 is 1.
HCF(48, 81, 86) = 1
HCF of 48, 81, 86 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 48, 81, 86 is 1.
Highest Common Factor of 48,81,86 is 1
Step 1: Since 81 > 48, we apply the division lemma to 81 and 48, to get
81 = 48 x 1 + 33
Step 2: Since the reminder 48 ≠ 0, we apply division lemma to 33 and 48, to get
48 = 33 x 1 + 15
Step 3: We consider the new divisor 33 and the new remainder 15, and apply the division lemma to get
33 = 15 x 2 + 3
We consider the new divisor 15 and the new remainder 3, and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 48 and 81 is 3
Notice that 3 = HCF(15,3) = HCF(33,15) = HCF(48,33) = HCF(81,48) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 86 > 3, we apply the division lemma to 86 and 3, to get
86 = 3 x 28 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 86 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(86,3) .
