HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 783, 481, 768 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 783, 481, 768 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 783, 481, 768 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 783, 481, 768 is 1.

HCF(783, 481, 768) = 1

HCF of 783, 481, 768 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 783, 481, 768 is 1.

Highest Common Factor of 783,481,768 using Euclid's algorithm

Highest Common Factor of 783,481,768 is 1

Step 1: Since 783 > 481, we apply the division lemma to 783 and 481, to get

783 = 481 x 1 + 302

Step 2: Since the reminder 481 ≠ 0, we apply division lemma to 302 and 481, to get

481 = 302 x 1 + 179

Step 3: We consider the new divisor 302 and the new remainder 179, and apply the division lemma to get

302 = 179 x 1 + 123

We consider the new divisor 179 and the new remainder 123,and apply the division lemma to get

179 = 123 x 1 + 56

We consider the new divisor 123 and the new remainder 56,and apply the division lemma to get

123 = 56 x 2 + 11

We consider the new divisor 56 and the new remainder 11,and apply the division lemma to get

56 = 11 x 5 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 783 and 481 is 1

Notice that 1 = HCF(11,1) = HCF(56,11) = HCF(123,56) = HCF(179,123) = HCF(302,179) = HCF(481,302) = HCF(783,481) .

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

Step 1: Since 768 > 1, we apply the division lemma to 768 and 1, to get

768 = 1 x 768 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 768 is 1

Notice that 1 = HCF(768,1) .
