Given numbers are 272,980,406,805,655

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

The LCM of 272,980,406,805,655 is 5822803280.

Find LCM of 272,980,406,805,655 with Prime Factorization

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

2 x 2 x 5 x 7 x 68 x 7 x 29 x 23 x 131 = 5822803280

Therefore, the lowest common multiple of 272,980,406,805,655 is 5822803280.

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.

272 x 980 x 406 x 805 x 655 = 57063472144000

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.

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

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

805 : 1, 5, 7, 23, 35, 115, 161, 805

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 272,980,406,805,655, is 1.

Now, the common factors can be found like this.

272:2x 2x 2x 2x 17

980:2x 2x 5x 7x 7

406:2x 7x 29

805:5x 7x 23

655:5x 131

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 5x 5x 7x 7 = 9800

Therefore, the value for common factors is 9800.

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 = 57063472144000/(1x9800)

LCM = 57063472144000/9800

LCM = 5822803280

Thus, we can understand that the LCM of 272,980,406,805,655 is 5822803280.
