HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 251, 605, 988 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 251, 605, 988 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 251, 605, 988 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 251, 605, 988 is 1.

HCF(251, 605, 988) = 1

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

HCF of:

Highest common factor (HCF) of 251, 605, 988 is 1.

Highest Common Factor of 251,605,988 using Euclid's algorithm

Highest Common Factor of 251,605,988 is 1

Step 1: Since 605 > 251, we apply the division lemma to 605 and 251, to get

605 = 251 x 2 + 103

Step 2: Since the reminder 251 ≠ 0, we apply division lemma to 103 and 251, to get

251 = 103 x 2 + 45

Step 3: We consider the new divisor 103 and the new remainder 45, and apply the division lemma to get

103 = 45 x 2 + 13

We consider the new divisor 45 and the new remainder 13,and apply the division lemma to get

45 = 13 x 3 + 6

We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get

13 = 6 x 2 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 251 and 605 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(45,13) = HCF(103,45) = HCF(251,103) = HCF(605,251) .

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

Step 1: Since 988 > 1, we apply the division lemma to 988 and 1, to get

988 = 1 x 988 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 988 is 1

Notice that 1 = HCF(988,1) .
