HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 339, 128 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 339, 128 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 339, 128 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 339, 128 is 1.

HCF(339, 128) = 1

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

HCF of:

Highest common factor (HCF) of 339, 128 is 1.

Highest Common Factor of 339,128 using Euclid's algorithm

Highest Common Factor of 339,128 is 1

Step 1: Since 339 > 128, we apply the division lemma to 339 and 128, to get

339 = 128 x 2 + 83

Step 2: Since the reminder 128 ≠ 0, we apply division lemma to 83 and 128, to get

128 = 83 x 1 + 45

Step 3: We consider the new divisor 83 and the new remainder 45, and apply the division lemma to get

83 = 45 x 1 + 38

We consider the new divisor 45 and the new remainder 38,and apply the division lemma to get

45 = 38 x 1 + 7

We consider the new divisor 38 and the new remainder 7,and apply the division lemma to get

38 = 7 x 5 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 1

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 339 and 128 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(38,7) = HCF(45,38) = HCF(83,45) = HCF(128,83) = HCF(339,128) .
