HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 257, 339, 312 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 257, 339, 312 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 257, 339, 312 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 257, 339, 312 is 1.

HCF(257, 339, 312) = 1

HCF of 257, 339, 312 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 257, 339, 312 is 1.

Highest Common Factor of 257,339,312 using Euclid's algorithm

Highest Common Factor of 257,339,312 is 1

Step 1: Since 339 > 257, we apply the division lemma to 339 and 257, to get

339 = 257 x 1 + 82

Step 2: Since the reminder 257 ≠ 0, we apply division lemma to 82 and 257, to get

257 = 82 x 3 + 11

Step 3: We consider the new divisor 82 and the new remainder 11, and apply the division lemma to get

82 = 11 x 7 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 257 and 339 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(82,11) = HCF(257,82) = HCF(339,257) .

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

Step 1: Since 312 > 1, we apply the division lemma to 312 and 1, to get

312 = 1 x 312 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 312 is 1

Notice that 1 = HCF(312,1) .
