HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 338, 542, 127 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 338, 542, 127 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 338, 542, 127 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 338, 542, 127 is 1.

HCF(338, 542, 127) = 1

Highest common factor (HCF) of 338, 542, 127 is 1.

Highest Common Factor of 338,542,127 using Euclid's algorithm

Highest Common Factor of 338,542,127 is 1

Step 1: Since 542 > 338, we apply the division lemma to 542 and 338, to get

542 = 338 x 1 + 204

Step 2: Since the reminder 338 ≠ 0, we apply division lemma to 204 and 338, to get

338 = 204 x 1 + 134

Step 3: We consider the new divisor 204 and the new remainder 134, and apply the division lemma to get

204 = 134 x 1 + 70

We consider the new divisor 134 and the new remainder 70,and apply the division lemma to get

134 = 70 x 1 + 64

We consider the new divisor 70 and the new remainder 64,and apply the division lemma to get

70 = 64 x 1 + 6

We consider the new divisor 64 and the new remainder 6,and apply the division lemma to get

64 = 6 x 10 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 338 and 542 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(64,6) = HCF(70,64) = HCF(134,70) = HCF(204,134) = HCF(338,204) = HCF(542,338) .

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

Step 1: Since 127 > 2, we apply the division lemma to 127 and 2, to get

127 = 2 x 63 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 127 is 1

Notice that 1 = HCF(2,1) = HCF(127,2) .
