HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 487, 955, 893 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 487, 955, 893 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, 955, 893 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, 955, 893 is 1.

HCF(487, 955, 893) = 1

Highest common factor (HCF) of 487, 955, 893 is 1.

Highest Common Factor of 487,955,893 using Euclid's algorithm

Highest Common Factor of 487,955,893 is 1

Step 1: Since 955 > 487, we apply the division lemma to 955 and 487, to get

955 = 487 x 1 + 468

Step 2: Since the reminder 487 ≠ 0, we apply division lemma to 468 and 487, to get

487 = 468 x 1 + 19

Step 3: We consider the new divisor 468 and the new remainder 19, and apply the division lemma to get

468 = 19 x 24 + 12

We consider the new divisor 19 and the new remainder 12,and apply the division lemma to get

19 = 12 x 1 + 7

We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get

12 = 7 x 1 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 487 and 955 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(19,12) = HCF(468,19) = HCF(487,468) = HCF(955,487) .

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

Step 1: Since 893 > 1, we apply the division lemma to 893 and 1, to get

893 = 1 x 893 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 893 is 1

Notice that 1 = HCF(893,1) .
