HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 171, 513, 647, 54 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 171, 513, 647, 54 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 171, 513, 647, 54 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 171, 513, 647, 54 is 1.

HCF(171, 513, 647, 54) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 171, 513, 647, 54 is 1.

Highest Common Factor of 171,513,647,54 using Euclid's algorithm

Highest Common Factor of 171,513,647,54 is 1

Step 1: Since 513 > 171, we apply the division lemma to 513 and 171, to get

513 = 171 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 171, the HCF of 171 and 513 is 171

Notice that 171 = HCF(513,171) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 647 > 171, we apply the division lemma to 647 and 171, to get

647 = 171 x 3 + 134

Step 2: Since the reminder 171 ≠ 0, we apply division lemma to 134 and 171, to get

171 = 134 x 1 + 37

Step 3: We consider the new divisor 134 and the new remainder 37, and apply the division lemma to get

134 = 37 x 3 + 23

We consider the new divisor 37 and the new remainder 23,and apply the division lemma to get

37 = 23 x 1 + 14

We consider the new divisor 23 and the new remainder 14,and apply the division lemma to get

23 = 14 x 1 + 9

We consider the new divisor 14 and the new remainder 9,and apply the division lemma to get

14 = 9 x 1 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 171 and 647 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(23,14) = HCF(37,23) = HCF(134,37) = HCF(171,134) = HCF(647,171) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 54 > 1, we apply the division lemma to 54 and 1, to get

54 = 1 x 54 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 54 is 1

Notice that 1 = HCF(54,1) .
