HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 548, 787, 493 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 548, 787, 493 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 548, 787, 493 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 548, 787, 493 is 1.

HCF(548, 787, 493) = 1

Highest common factor (HCF) of 548, 787, 493 is 1.

Highest Common Factor of 548,787,493 using Euclid's algorithm

Highest Common Factor of 548,787,493 is 1

Step 1: Since 787 > 548, we apply the division lemma to 787 and 548, to get

787 = 548 x 1 + 239

Step 2: Since the reminder 548 ≠ 0, we apply division lemma to 239 and 548, to get

548 = 239 x 2 + 70

Step 3: We consider the new divisor 239 and the new remainder 70, and apply the division lemma to get

239 = 70 x 3 + 29

We consider the new divisor 70 and the new remainder 29,and apply the division lemma to get

70 = 29 x 2 + 12

We consider the new divisor 29 and the new remainder 12,and apply the division lemma to get

29 = 12 x 2 + 5

We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get

12 = 5 x 2 + 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 548 and 787 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(29,12) = HCF(70,29) = HCF(239,70) = HCF(548,239) = HCF(787,548) .

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

Step 1: Since 493 > 1, we apply the division lemma to 493 and 1, to get

493 = 1 x 493 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 493 is 1

Notice that 1 = HCF(493,1) .
