HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 517, 718, 749 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 517, 718, 749 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 517, 718, 749 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 517, 718, 749 is 1.

HCF(517, 718, 749) = 1

Highest common factor (HCF) of 517, 718, 749 is 1.

Highest Common Factor of 517,718,749 using Euclid's algorithm

Highest Common Factor of 517,718,749 is 1

Step 1: Since 718 > 517, we apply the division lemma to 718 and 517, to get

718 = 517 x 1 + 201

Step 2: Since the reminder 517 ≠ 0, we apply division lemma to 201 and 517, to get

517 = 201 x 2 + 115

Step 3: We consider the new divisor 201 and the new remainder 115, and apply the division lemma to get

201 = 115 x 1 + 86

We consider the new divisor 115 and the new remainder 86,and apply the division lemma to get

115 = 86 x 1 + 29

We consider the new divisor 86 and the new remainder 29,and apply the division lemma to get

86 = 29 x 2 + 28

We consider the new divisor 29 and the new remainder 28,and apply the division lemma to get

29 = 28 x 1 + 1

We consider the new divisor 28 and the new remainder 1,and apply the division lemma to get

28 = 1 x 28 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 517 and 718 is 1

Notice that 1 = HCF(28,1) = HCF(29,28) = HCF(86,29) = HCF(115,86) = HCF(201,115) = HCF(517,201) = HCF(718,517) .


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

Step 1: Since 749 > 1, we apply the division lemma to 749 and 1, to get

749 = 1 x 749 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 749 is 1

Notice that 1 = HCF(749,1) .
