HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 149, 989, 518 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 149, 989, 518 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 149, 989, 518 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 149, 989, 518 is 1.

HCF(149, 989, 518) = 1

HCF of 149, 989, 518 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 149, 989, 518 is 1.

Highest Common Factor of 149,989,518 using Euclid's algorithm

Highest Common Factor of 149,989,518 is 1

Step 1: Since 989 > 149, we apply the division lemma to 989 and 149, to get

989 = 149 x 6 + 95

Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 95 and 149, to get

149 = 95 x 1 + 54

Step 3: We consider the new divisor 95 and the new remainder 54, and apply the division lemma to get

95 = 54 x 1 + 41

We consider the new divisor 54 and the new remainder 41,and apply the division lemma to get

54 = 41 x 1 + 13

We consider the new divisor 41 and the new remainder 13,and apply the division lemma to get

41 = 13 x 3 + 2

We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get

13 = 2 x 6 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 149 and 989 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(41,13) = HCF(54,41) = HCF(95,54) = HCF(149,95) = HCF(989,149) .

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

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

518 = 1 x 518 + 0

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

Notice that 1 = HCF(518,1) .
