HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 317, 205, 555, 982 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 317, 205, 555, 982 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 317, 205, 555, 982 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 317, 205, 555, 982 is 1.

HCF(317, 205, 555, 982) = 1

Highest Common Factor of 317,205,555,982 using Euclid's algorithm

Highest Common Factor of 317,205,555,982 is 1

Step 1: Since 317 > 205, we apply the division lemma to 317 and 205, to get

317 = 205 x 1 + 112

Step 2: Since the reminder 205 ≠ 0, we apply division lemma to 112 and 205, to get

205 = 112 x 1 + 93

Step 3: We consider the new divisor 112 and the new remainder 93, and apply the division lemma to get

112 = 93 x 1 + 19

We consider the new divisor 93 and the new remainder 19,and apply the division lemma to get

93 = 19 x 4 + 17

We consider the new divisor 19 and the new remainder 17,and apply the division lemma to get

19 = 17 x 1 + 2

We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get

17 = 2 x 8 + 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 317 and 205 is 1

Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(19,17) = HCF(93,19) = HCF(112,93) = HCF(205,112) = HCF(317,205) .

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

Step 1: Since 555 > 1, we apply the division lemma to 555 and 1, to get

555 = 1 x 555 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 555 is 1

Notice that 1 = HCF(555,1) .

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

Step 1: Since 982 > 1, we apply the division lemma to 982 and 1, to get

982 = 1 x 982 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 982 is 1

Notice that 1 = HCF(982,1) .
