HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 173, 987, 412 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 173, 987, 412 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 173, 987, 412 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 173, 987, 412 is 1.

HCF(173, 987, 412) = 1

Highest common factor (HCF) of 173, 987, 412 is 1.

Highest Common Factor of 173,987,412 using Euclid's algorithm

Highest Common Factor of 173,987,412 is 1

Step 1: Since 987 > 173, we apply the division lemma to 987 and 173, to get

987 = 173 x 5 + 122

Step 2: Since the reminder 173 ≠ 0, we apply division lemma to 122 and 173, to get

173 = 122 x 1 + 51

Step 3: We consider the new divisor 122 and the new remainder 51, and apply the division lemma to get

122 = 51 x 2 + 20

We consider the new divisor 51 and the new remainder 20,and apply the division lemma to get

51 = 20 x 2 + 11

We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get

20 = 11 x 1 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 173 and 987 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(51,20) = HCF(122,51) = HCF(173,122) = HCF(987,173) .

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

Step 1: Since 412 > 1, we apply the division lemma to 412 and 1, to get

412 = 1 x 412 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 412 is 1

Notice that 1 = HCF(412,1) .
