HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 994, 450, 517 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 994, 450, 517 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 994, 450, 517 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 994, 450, 517 is 1.

HCF(994, 450, 517) = 1

Highest Common Factor of 994,450,517 using Euclid's algorithm

Highest Common Factor of 994,450,517 is 1

Step 1: Since 994 > 450, we apply the division lemma to 994 and 450, to get

994 = 450 x 2 + 94

Step 2: Since the reminder 450 ≠ 0, we apply division lemma to 94 and 450, to get

450 = 94 x 4 + 74

Step 3: We consider the new divisor 94 and the new remainder 74, and apply the division lemma to get

94 = 74 x 1 + 20

We consider the new divisor 74 and the new remainder 20,and apply the division lemma to get

74 = 20 x 3 + 14

We consider the new divisor 20 and the new remainder 14,and apply the division lemma to get

20 = 14 x 1 + 6

We consider the new divisor 14 and the new remainder 6,and apply the division lemma to get

14 = 6 x 2 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 994 and 450 is 2

Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(20,14) = HCF(74,20) = HCF(94,74) = HCF(450,94) = HCF(994,450) .

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

Step 1: Since 517 > 2, we apply the division lemma to 517 and 2, to get

517 = 2 x 258 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 517 is 1

Notice that 1 = HCF(2,1) = HCF(517,2) .
