HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 425, 518, 917 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 425, 518, 917 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 425, 518, 917 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 425, 518, 917 is 1.

HCF(425, 518, 917) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 425, 518, 917 is 1.

Highest Common Factor of 425,518,917 using Euclid's algorithm

Highest Common Factor of 425,518,917 is 1

Step 1: Since 518 > 425, we apply the division lemma to 518 and 425, to get

518 = 425 x 1 + 93

Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 93 and 425, to get

425 = 93 x 4 + 53

Step 3: We consider the new divisor 93 and the new remainder 53, and apply the division lemma to get

93 = 53 x 1 + 40

We consider the new divisor 53 and the new remainder 40,and apply the division lemma to get

53 = 40 x 1 + 13

We consider the new divisor 40 and the new remainder 13,and apply the division lemma to get

40 = 13 x 3 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 425 and 518 is 1

Notice that 1 = HCF(13,1) = HCF(40,13) = HCF(53,40) = HCF(93,53) = HCF(425,93) = HCF(518,425) .

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

Step 1: Since 917 > 1, we apply the division lemma to 917 and 1, to get

917 = 1 x 917 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 917 is 1

Notice that 1 = HCF(917,1) .
