HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 81, 330, 514 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 81, 330, 514 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 81, 330, 514 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 81, 330, 514 is 1.
HCF(81, 330, 514) = 1
HCF of 81, 330, 514 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 81, 330, 514 is 1.
Highest Common Factor of 81,330,514 is 1
Step 1: Since 330 > 81, we apply the division lemma to 330 and 81, to get
330 = 81 x 4 + 6
Step 2: Since the reminder 81 ≠ 0, we apply division lemma to 6 and 81, to get
81 = 6 x 13 + 3
Step 3: We consider the new divisor 6 and the new remainder 3, and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 81 and 330 is 3
Notice that 3 = HCF(6,3) = HCF(81,6) = HCF(330,81) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 514 > 3, we apply the division lemma to 514 and 3, to get
514 = 3 x 171 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 514 is 1
Notice that 1 = HCF(3,1) = HCF(514,3) .
