HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 663, 583, 551 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 663, 583, 551 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 663, 583, 551 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 663, 583, 551 is 1.

HCF(663, 583, 551) = 1

HCF of 663, 583, 551 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 663, 583, 551 is 1.

Highest Common Factor of 663,583,551 using Euclid's algorithm

Highest Common Factor of 663,583,551 is 1

Step 1: Since 663 > 583, we apply the division lemma to 663 and 583, to get

663 = 583 x 1 + 80

Step 2: Since the reminder 583 ≠ 0, we apply division lemma to 80 and 583, to get

583 = 80 x 7 + 23

Step 3: We consider the new divisor 80 and the new remainder 23, and apply the division lemma to get

80 = 23 x 3 + 11

We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get

23 = 11 x 2 + 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 663 and 583 is 1

Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(80,23) = HCF(583,80) = HCF(663,583) .

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

Step 1: Since 551 > 1, we apply the division lemma to 551 and 1, to get

551 = 1 x 551 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 551 is 1

Notice that 1 = HCF(551,1) .
