HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 558, 860, 487 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 558, 860, 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 558, 860, 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 558, 860, 487 is 1.

HCF(558, 860, 487) = 1

Highest common factor (HCF) of 558, 860, 487 is 1.

Highest Common Factor of 558,860,487 using Euclid's algorithm

Highest Common Factor of 558,860,487 is 1

Step 1: Since 860 > 558, we apply the division lemma to 860 and 558, to get

860 = 558 x 1 + 302

Step 2: Since the reminder 558 ≠ 0, we apply division lemma to 302 and 558, to get

558 = 302 x 1 + 256

Step 3: We consider the new divisor 302 and the new remainder 256, and apply the division lemma to get

302 = 256 x 1 + 46

We consider the new divisor 256 and the new remainder 46,and apply the division lemma to get

256 = 46 x 5 + 26

We consider the new divisor 46 and the new remainder 26,and apply the division lemma to get

46 = 26 x 1 + 20

We consider the new divisor 26 and the new remainder 20,and apply the division lemma to get

26 = 20 x 1 + 6

We consider the new divisor 20 and the new remainder 6,and apply the division lemma to get

20 = 6 x 3 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 558 and 860 is 2

Notice that 2 = HCF(6,2) = HCF(20,6) = HCF(26,20) = HCF(46,26) = HCF(256,46) = HCF(302,256) = HCF(558,302) = HCF(860,558) .

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

Step 1: Since 487 > 2, we apply the division lemma to 487 and 2, to get

487 = 2 x 243 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 487 is 1

Notice that 1 = HCF(2,1) = HCF(487,2) .
