HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 640, 379, 548 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 640, 379, 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 640, 379, 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 640, 379, 548 is 1.

HCF(640, 379, 548) = 1

HCF of 640, 379, 548 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 640, 379, 548 is 1.

Highest Common Factor of 640,379,548 using Euclid's algorithm

Highest Common Factor of 640,379,548 is 1

Step 1: Since 640 > 379, we apply the division lemma to 640 and 379, to get

640 = 379 x 1 + 261

Step 2: Since the reminder 379 ≠ 0, we apply division lemma to 261 and 379, to get

379 = 261 x 1 + 118

Step 3: We consider the new divisor 261 and the new remainder 118, and apply the division lemma to get

261 = 118 x 2 + 25

We consider the new divisor 118 and the new remainder 25,and apply the division lemma to get

118 = 25 x 4 + 18

We consider the new divisor 25 and the new remainder 18,and apply the division lemma to get

25 = 18 x 1 + 7

We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get

18 = 7 x 2 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 640 and 379 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(25,18) = HCF(118,25) = HCF(261,118) = HCF(379,261) = HCF(640,379) .

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) .
