HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 468, 557, 765 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 468, 557, 765 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 468, 557, 765 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 468, 557, 765 is 1.

HCF(468, 557, 765) = 1

HCF of 468, 557, 765 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 468, 557, 765 is 1.

Highest Common Factor of 468,557,765 using Euclid's algorithm

Highest Common Factor of 468,557,765 is 1

Step 1: Since 557 > 468, we apply the division lemma to 557 and 468, to get

557 = 468 x 1 + 89

Step 2: Since the reminder 468 ≠ 0, we apply division lemma to 89 and 468, to get

468 = 89 x 5 + 23

Step 3: We consider the new divisor 89 and the new remainder 23, and apply the division lemma to get

89 = 23 x 3 + 20

We consider the new divisor 23 and the new remainder 20,and apply the division lemma to get

23 = 20 x 1 + 3

We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get

20 = 3 x 6 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 468 and 557 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(23,20) = HCF(89,23) = HCF(468,89) = HCF(557,468) .

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

Step 1: Since 765 > 1, we apply the division lemma to 765 and 1, to get

765 = 1 x 765 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 765 is 1

Notice that 1 = HCF(765,1) .
