HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 317, 485, 94 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 317, 485, 94 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, 485, 94 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, 485, 94 is 1.

HCF(317, 485, 94) = 1

Highest common factor (HCF) of 317, 485, 94 is 1.

Highest Common Factor of 317,485,94 using Euclid's algorithm

Highest Common Factor of 317,485,94 is 1

Step 1: Since 485 > 317, we apply the division lemma to 485 and 317, to get

485 = 317 x 1 + 168

Step 2: Since the reminder 317 ≠ 0, we apply division lemma to 168 and 317, to get

317 = 168 x 1 + 149

Step 3: We consider the new divisor 168 and the new remainder 149, and apply the division lemma to get

168 = 149 x 1 + 19

We consider the new divisor 149 and the new remainder 19,and apply the division lemma to get

149 = 19 x 7 + 16

We consider the new divisor 19 and the new remainder 16,and apply the division lemma to get

19 = 16 x 1 + 3

We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get

16 = 3 x 5 + 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 317 and 485 is 1

Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(19,16) = HCF(149,19) = HCF(168,149) = HCF(317,168) = HCF(485,317) .

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

Step 1: Since 94 > 1, we apply the division lemma to 94 and 1, to get

94 = 1 x 94 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 94 is 1

Notice that 1 = HCF(94,1) .
