HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 2347, 1442, 78034 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 2347, 1442, 78034 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 2347, 1442, 78034 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 2347, 1442, 78034 is 1.

HCF(2347, 1442, 78034) = 1

Highest common factor (HCF) of 2347, 1442, 78034 is 1.

Highest Common Factor of 2347,1442,78034 using Euclid's algorithm

Highest Common Factor of 2347,1442,78034 is 1

Step 1: Since 2347 > 1442, we apply the division lemma to 2347 and 1442, to get

2347 = 1442 x 1 + 905

Step 2: Since the reminder 1442 ≠ 0, we apply division lemma to 905 and 1442, to get

1442 = 905 x 1 + 537

Step 3: We consider the new divisor 905 and the new remainder 537, and apply the division lemma to get

905 = 537 x 1 + 368

We consider the new divisor 537 and the new remainder 368,and apply the division lemma to get

537 = 368 x 1 + 169

We consider the new divisor 368 and the new remainder 169,and apply the division lemma to get

368 = 169 x 2 + 30

We consider the new divisor 169 and the new remainder 30,and apply the division lemma to get

169 = 30 x 5 + 19

We consider the new divisor 30 and the new remainder 19,and apply the division lemma to get

30 = 19 x 1 + 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 2347 and 1442 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(19,11) = HCF(30,19) = HCF(169,30) = HCF(368,169) = HCF(537,368) = HCF(905,537) = HCF(1442,905) = HCF(2347,1442) .

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

Step 1: Since 78034 > 1, we apply the division lemma to 78034 and 1, to get

78034 = 1 x 78034 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 78034 is 1

Notice that 1 = HCF(78034,1) .
