HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 515, 385, 523 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 515, 385, 523 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 515, 385, 523 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 515, 385, 523 is 1.

HCF(515, 385, 523) = 1

HCF of 515, 385, 523 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 515, 385, 523 is 1.

Highest Common Factor of 515,385,523 using Euclid's algorithm

Highest Common Factor of 515,385,523 is 1

Step 1: Since 515 > 385, we apply the division lemma to 515 and 385, to get

515 = 385 x 1 + 130

Step 2: Since the reminder 385 ≠ 0, we apply division lemma to 130 and 385, to get

385 = 130 x 2 + 125

Step 3: We consider the new divisor 130 and the new remainder 125, and apply the division lemma to get

130 = 125 x 1 + 5

We consider the new divisor 125 and the new remainder 5, and apply the division lemma to get

125 = 5 x 25 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 515 and 385 is 5

Notice that 5 = HCF(125,5) = HCF(130,125) = HCF(385,130) = HCF(515,385) .

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

Step 1: Since 523 > 5, we apply the division lemma to 523 and 5, to get

523 = 5 x 104 + 3

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get

5 = 3 x 1 + 2

Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get

3 = 2 x 1 + 1

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 5 and 523 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(523,5) .
