HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 349, 134, 138 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 349, 134, 138 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 349, 134, 138 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 349, 134, 138 is 1.

HCF(349, 134, 138) = 1

HCF of 349, 134, 138 using Euclid's algorithm

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

Highest common factor (HCF) of 349, 134, 138 is 1.

Highest Common Factor of 349,134,138 using Euclid's algorithm

Highest Common Factor of 349,134,138 is 1

Step 1: Since 349 > 134, we apply the division lemma to 349 and 134, to get

349 = 134 x 2 + 81

Step 2: Since the reminder 134 ≠ 0, we apply division lemma to 81 and 134, to get

134 = 81 x 1 + 53

Step 3: We consider the new divisor 81 and the new remainder 53, and apply the division lemma to get

81 = 53 x 1 + 28

We consider the new divisor 53 and the new remainder 28,and apply the division lemma to get

53 = 28 x 1 + 25

We consider the new divisor 28 and the new remainder 25,and apply the division lemma to get

28 = 25 x 1 + 3

We consider the new divisor 25 and the new remainder 3,and apply the division lemma to get

25 = 3 x 8 + 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 349 and 134 is 1

Notice that 1 = HCF(3,1) = HCF(25,3) = HCF(28,25) = HCF(53,28) = HCF(81,53) = HCF(134,81) = HCF(349,134) .

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

Step 1: Since 138 > 1, we apply the division lemma to 138 and 1, to get

138 = 1 x 138 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 138 is 1

Notice that 1 = HCF(138,1) .
