HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 404, 785, 102 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 404, 785, 102 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 404, 785, 102 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 404, 785, 102 is 1.

HCF(404, 785, 102) = 1

Highest common factor (HCF) of 404, 785, 102 is 1.

Highest Common Factor of 404,785,102 using Euclid's algorithm

Highest Common Factor of 404,785,102 is 1

Step 1: Since 785 > 404, we apply the division lemma to 785 and 404, to get

785 = 404 x 1 + 381

Step 2: Since the reminder 404 ≠ 0, we apply division lemma to 381 and 404, to get

404 = 381 x 1 + 23

Step 3: We consider the new divisor 381 and the new remainder 23, and apply the division lemma to get

381 = 23 x 16 + 13

We consider the new divisor 23 and the new remainder 13,and apply the division lemma to get

23 = 13 x 1 + 10

We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get

13 = 10 x 1 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 404 and 785 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(23,13) = HCF(381,23) = HCF(404,381) = HCF(785,404) .

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

Step 1: Since 102 > 1, we apply the division lemma to 102 and 1, to get

102 = 1 x 102 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 102 is 1

Notice that 1 = HCF(102,1) .
