HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 348, 728, 515 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 348, 728, 515 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 348, 728, 515 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 348, 728, 515 is 1.

HCF(348, 728, 515) = 1

HCF of 348, 728, 515 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 348, 728, 515 is 1.

Highest Common Factor of 348,728,515 using Euclid's algorithm

Highest Common Factor of 348,728,515 is 1

Step 1: Since 728 > 348, we apply the division lemma to 728 and 348, to get

728 = 348 x 2 + 32

Step 2: Since the reminder 348 ≠ 0, we apply division lemma to 32 and 348, to get

348 = 32 x 10 + 28

Step 3: We consider the new divisor 32 and the new remainder 28, and apply the division lemma to get

32 = 28 x 1 + 4

We consider the new divisor 28 and the new remainder 4, and apply the division lemma to get

28 = 4 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 348 and 728 is 4

Notice that 4 = HCF(28,4) = HCF(32,28) = HCF(348,32) = HCF(728,348) .

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

Step 1: Since 515 > 4, we apply the division lemma to 515 and 4, to get

515 = 4 x 128 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma 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 4 and 515 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(515,4) .
