HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 792, 724, 517 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 792, 724, 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 792, 724, 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 792, 724, 517 is 1.

HCF(792, 724, 517) = 1

Highest common factor (HCF) of 792, 724, 517 is 1.

Highest Common Factor of 792,724,517 using Euclid's algorithm

Highest Common Factor of 792,724,517 is 1

Step 1: Since 792 > 724, we apply the division lemma to 792 and 724, to get

792 = 724 x 1 + 68

Step 2: Since the reminder 724 ≠ 0, we apply division lemma to 68 and 724, to get

724 = 68 x 10 + 44

Step 3: We consider the new divisor 68 and the new remainder 44, and apply the division lemma to get

68 = 44 x 1 + 24

We consider the new divisor 44 and the new remainder 24,and apply the division lemma to get

44 = 24 x 1 + 20

We consider the new divisor 24 and the new remainder 20,and apply the division lemma to get

24 = 20 x 1 + 4

We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get

20 = 4 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 792 and 724 is 4

Notice that 4 = HCF(20,4) = HCF(24,20) = HCF(44,24) = HCF(68,44) = HCF(724,68) = HCF(792,724) .

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

Step 1: Since 517 > 4, we apply the division lemma to 517 and 4, to get

517 = 4 x 129 + 1

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 517 is 1

Notice that 1 = HCF(4,1) = HCF(517,4) .
