HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 165, 634, 487 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 165, 634, 487 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 165, 634, 487 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 165, 634, 487 is 1.

HCF(165, 634, 487) = 1

HCF of 165, 634, 487 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 165, 634, 487 is 1.

Highest Common Factor of 165,634,487 using Euclid's algorithm

Highest Common Factor of 165,634,487 is 1

Step 1: Since 634 > 165, we apply the division lemma to 634 and 165, to get

634 = 165 x 3 + 139

Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 139 and 165, to get

165 = 139 x 1 + 26

Step 3: We consider the new divisor 139 and the new remainder 26, and apply the division lemma to get

139 = 26 x 5 + 9

We consider the new divisor 26 and the new remainder 9,and apply the division lemma to get

26 = 9 x 2 + 8

We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get

9 = 8 x 1 + 1

We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get

8 = 1 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 165 and 634 is 1

Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(26,9) = HCF(139,26) = HCF(165,139) = HCF(634,165) .

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

Step 1: Since 487 > 1, we apply the division lemma to 487 and 1, to get

487 = 1 x 487 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 487 is 1

Notice that 1 = HCF(487,1) .
