HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 348, 221, 197 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 348, 221, 197 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, 221, 197 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, 221, 197 is 1.

HCF(348, 221, 197) = 1

HCF of 348, 221, 197 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, 221, 197 is 1.

Highest Common Factor of 348,221,197 using Euclid's algorithm

Highest Common Factor of 348,221,197 is 1

Step 1: Since 348 > 221, we apply the division lemma to 348 and 221, to get

348 = 221 x 1 + 127

Step 2: Since the reminder 221 ≠ 0, we apply division lemma to 127 and 221, to get

221 = 127 x 1 + 94

Step 3: We consider the new divisor 127 and the new remainder 94, and apply the division lemma to get

127 = 94 x 1 + 33

We consider the new divisor 94 and the new remainder 33,and apply the division lemma to get

94 = 33 x 2 + 28

We consider the new divisor 33 and the new remainder 28,and apply the division lemma to get

33 = 28 x 1 + 5

We consider the new divisor 28 and the new remainder 5,and apply the division lemma to get

28 = 5 x 5 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 348 and 221 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(28,5) = HCF(33,28) = HCF(94,33) = HCF(127,94) = HCF(221,127) = HCF(348,221) .

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

Step 1: Since 197 > 1, we apply the division lemma to 197 and 1, to get

197 = 1 x 197 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 197 is 1

Notice that 1 = HCF(197,1) .
