Given numbers are 388,406,154,440,607

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

The LCM of 388,406,154,440,607 is 5259072280.

Find LCM of 388,406,154,440,607 with Prime Factorization

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

2 x 2 x 7 x 11 x 97 x 29 x 1 x 10 x 607 = 5259072280

Therefore, the lowest common multiple of 388,406,154,440,607 is 5259072280.

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.

388 x 406 x 154 x 440 x 607 = 6479177048960

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.

388 : 1, 2, 4, 97, 194, 388

406 : 1, 2, 7, 14, 29, 58, 203, 406

154 : 1, 2, 7, 11, 14, 22, 77, 154

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

607 : 1, 607

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,406,154,440,607, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

406:2x 7x 29

154:2x 7x 11

440:2x 2x 2x 5x 11

607:607

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 2x 2x 7x 11 = 1232

Therefore, the value for common factors is 1232.

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 = 6479177048960/(1x1232)

LCM = 6479177048960/1232

LCM = 5259072280

Thus, we can understand that the LCM of 388,406,154,440,607 is 5259072280.
