HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 193, 473, 278, 347 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 193, 473, 278, 347 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 193, 473, 278, 347 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 193, 473, 278, 347 is 1.

HCF(193, 473, 278, 347) = 1

Highest Common Factor of 193,473,278,347 using Euclid's algorithm

Highest Common Factor of 193,473,278,347 is 1

Step 1: Since 473 > 193, we apply the division lemma to 473 and 193, to get

473 = 193 x 2 + 87

Step 2: Since the reminder 193 ≠ 0, we apply division lemma to 87 and 193, to get

193 = 87 x 2 + 19

Step 3: We consider the new divisor 87 and the new remainder 19, and apply the division lemma to get

87 = 19 x 4 + 11

We consider the new divisor 19 and the new remainder 11,and apply the division lemma to get

19 = 11 x 1 + 8

We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get

11 = 8 x 1 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 193 and 473 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(19,11) = HCF(87,19) = HCF(193,87) = HCF(473,193) .

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

Step 1: Since 278 > 1, we apply the division lemma to 278 and 1, to get

278 = 1 x 278 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 278 is 1

Notice that 1 = HCF(278,1) .

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

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

347 = 1 x 347 + 0

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

Notice that 1 = HCF(347,1) .
