HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 701, 858 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 487, 701, 858 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 487, 701, 858 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 487, 701, 858 is 1.

HCF(487, 701, 858) = 1

Highest common factor (HCF) of 487, 701, 858 is 1.

Highest Common Factor of 487,701,858 using Euclid's algorithm

Highest Common Factor of 487,701,858 is 1

Step 1: Since 701 > 487, we apply the division lemma to 701 and 487, to get

701 = 487 x 1 + 214

Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 214 and 487, to get

487 = 214 x 2 + 59

Step 3: We consider the new divisor 214 and the new remainder 59, and apply the division lemma to get

214 = 59 x 3 + 37

We consider the new divisor 59 and the new remainder 37,and apply the division lemma to get

59 = 37 x 1 + 22

We consider the new divisor 37 and the new remainder 22,and apply the division lemma to get

37 = 22 x 1 + 15

We consider the new divisor 22 and the new remainder 15,and apply the division lemma to get

22 = 15 x 1 + 7

We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get

15 = 7 x 2 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 487 and 701 is 1

Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(22,15) = HCF(37,22) = HCF(59,37) = HCF(214,59) = HCF(487,214) = HCF(701,487) .

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

Step 1: Since 858 > 1, we apply the division lemma to 858 and 1, to get

858 = 1 x 858 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 858 is 1

Notice that 1 = HCF(858,1) .
