HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 516, 339, 645 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 516, 339, 645 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 516, 339, 645 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 516, 339, 645 is 3.
HCF(516, 339, 645) = 3
HCF of 516, 339, 645 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 516, 339, 645 is 3.
Highest Common Factor of 516,339,645 is 3
Step 1: Since 516 > 339, we apply the division lemma to 516 and 339, to get
516 = 339 x 1 + 177
Step 2: Since the reminder 339 ≠ 0, we apply division lemma to 177 and 339, to get
339 = 177 x 1 + 162
Step 3: We consider the new divisor 177 and the new remainder 162, and apply the division lemma to get
177 = 162 x 1 + 15
We consider the new divisor 162 and the new remainder 15,and apply the division lemma to get
162 = 15 x 10 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 516 and 339 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(162,15) = HCF(177,162) = HCF(339,177) = HCF(516,339) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 645 > 3, we apply the division lemma to 645 and 3, to get
645 = 3 x 215 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 645 is 3
Notice that 3 = HCF(645,3) .
