HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 517, 626 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 517, 626 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, 626 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, 626 is 1.

HCF(517, 626) = 1

Highest common factor (HCF) of 517, 626 is 1.

Highest Common Factor of 517,626 using Euclid's algorithm

Highest Common Factor of 517,626 is 1

Step 1: Since 626 > 517, we apply the division lemma to 626 and 517, to get

626 = 517 x 1 + 109

Step 2: Since the reminder 517 ≠ 0, we apply division lemma to 109 and 517, to get

517 = 109 x 4 + 81

Step 3: We consider the new divisor 109 and the new remainder 81, and apply the division lemma to get

109 = 81 x 1 + 28

We consider the new divisor 81 and the new remainder 28,and apply the division lemma to get

81 = 28 x 2 + 25

We consider the new divisor 28 and the new remainder 25,and apply the division lemma to get

28 = 25 x 1 + 3

We consider the new divisor 25 and the new remainder 3,and apply the division lemma to get

25 = 3 x 8 + 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 517 and 626 is 1

Notice that 1 = HCF(3,1) = HCF(25,3) = HCF(28,25) = HCF(81,28) = HCF(109,81) = HCF(517,109) = HCF(626,517) .
