HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 347, 210, 238 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 347, 210, 238 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 347, 210, 238 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 347, 210, 238 is 1.

HCF(347, 210, 238) = 1

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

HCF of:

Highest common factor (HCF) of 347, 210, 238 is 1.

Highest Common Factor of 347,210,238 using Euclid's algorithm

Highest Common Factor of 347,210,238 is 1

Step 1: Since 347 > 210, we apply the division lemma to 347 and 210, to get

347 = 210 x 1 + 137

Step 2: Since the reminder 210 ≠ 0, we apply division lemma to 137 and 210, to get

210 = 137 x 1 + 73

Step 3: We consider the new divisor 137 and the new remainder 73, and apply the division lemma to get

137 = 73 x 1 + 64

We consider the new divisor 73 and the new remainder 64,and apply the division lemma to get

73 = 64 x 1 + 9

We consider the new divisor 64 and the new remainder 9,and apply the division lemma to get

64 = 9 x 7 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 347 and 210 is 1

Notice that 1 = HCF(9,1) = HCF(64,9) = HCF(73,64) = HCF(137,73) = HCF(210,137) = HCF(347,210) .

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

Step 1: Since 238 > 1, we apply the division lemma to 238 and 1, to get

238 = 1 x 238 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 238 is 1

Notice that 1 = HCF(238,1) .
