HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 781, 320, 548 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 781, 320, 548 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 781, 320, 548 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 781, 320, 548 is 1.

HCF(781, 320, 548) = 1

Highest common factor (HCF) of 781, 320, 548 is 1.

Highest Common Factor of 781,320,548 using Euclid's algorithm

Highest Common Factor of 781,320,548 is 1

Step 1: Since 781 > 320, we apply the division lemma to 781 and 320, to get

781 = 320 x 2 + 141

Step 2: Since the reminder 320 ≠ 0, we apply division lemma to 141 and 320, to get

320 = 141 x 2 + 38

Step 3: We consider the new divisor 141 and the new remainder 38, and apply the division lemma to get

141 = 38 x 3 + 27

We consider the new divisor 38 and the new remainder 27,and apply the division lemma to get

38 = 27 x 1 + 11

We consider the new divisor 27 and the new remainder 11,and apply the division lemma to get

27 = 11 x 2 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 781 and 320 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(27,11) = HCF(38,27) = HCF(141,38) = HCF(320,141) = HCF(781,320) .

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

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

548 = 1 x 548 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 548 is 1

Notice that 1 = HCF(548,1) .
