HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 258, 896, 787 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 258, 896, 787 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 258, 896, 787 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 258, 896, 787 is 1.

HCF(258, 896, 787) = 1

Highest common factor (HCF) of 258, 896, 787 is 1.

Highest Common Factor of 258,896,787 using Euclid's algorithm

Highest Common Factor of 258,896,787 is 1

Step 1: Since 896 > 258, we apply the division lemma to 896 and 258, to get

896 = 258 x 3 + 122

Step 2: Since the reminder 258 ≠ 0, we apply division lemma to 122 and 258, to get

258 = 122 x 2 + 14

Step 3: We consider the new divisor 122 and the new remainder 14, and apply the division lemma to get

122 = 14 x 8 + 10

We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get

14 = 10 x 1 + 4

We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get

10 = 4 x 2 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 258 and 896 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(122,14) = HCF(258,122) = HCF(896,258) .

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

Step 1: Since 787 > 2, we apply the division lemma to 787 and 2, to get

787 = 2 x 393 + 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 787 is 1

Notice that 1 = HCF(2,1) = HCF(787,2) .
