Given numbers are 548,386,978,815

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 548,386,978,815 is 258592980.

Find LCM of 548,386,978,815 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 163 x 274 x 193 x 3 x 5 = 258592980

Therefore, the lowest common multiple of 548,386,978,815 is 258592980.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

548 x 386 x 978 x 815 = 168602622960

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

548 : 1, 2, 4, 137, 274, 548

386 : 1, 2, 193, 386

978 : 1, 2, 3, 6, 163, 326, 489, 978

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 548,386,978,815, is 1.

Now, the common factors can be found like this.

548:2x 2x 137

386:2x 193

978:2x 3x 163

815:5x 163

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 163 = 652

Therefore, the value for common factors is 652.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 168602622960/(1x652)

LCM = 168602622960/652

LCM = 258592980

Thus, we can understand that the LCM of 548,386,978,815 is 258592980.
