HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 339, 387, 81 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 339, 387, 81 is 3 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 339, 387, 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 339, 387, 81 is 3.
HCF(339, 387, 81) = 3
HCF of 339, 387, 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 339, 387, 81 is 3.
Highest Common Factor of 339,387,81 is 3
Step 1: Since 387 > 339, we apply the division lemma to 387 and 339, to get
387 = 339 x 1 + 48
Step 2: Since the reminder 339 ≠ 0, we apply division lemma to 48 and 339, to get
339 = 48 x 7 + 3
Step 3: We consider the new divisor 48 and the new remainder 3, and apply the division lemma to get
48 = 3 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 339 and 387 is 3
Notice that 3 = HCF(48,3) = HCF(339,48) = HCF(387,339) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 81 > 3, we apply the division lemma to 81 and 3, to get
81 = 3 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 81 is 3
Notice that 3 = HCF(81,3) .
