Given numbers are 648,904,678,259,391

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

The LCM of 648,904,678,259,391 is 7415321256.

Find LCM of 648,904,678,259,391 with Prime Factorization

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

2 x 2 x 2 x 3 x 113 x 27 x 1 x 1 x 259 x 391 = 7415321256

Therefore, the lowest common multiple of 648,904,678,259,391 is 7415321256.

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.

648 x 904 x 678 x 259 x 391 = 40220702492544

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.

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

904 : 1, 2, 4, 8, 113, 226, 452, 904

678 : 1, 2, 3, 6, 113, 226, 339, 678

259 : 1, 7, 37, 259

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,904,678,259,391, is 1.

Now, the common factors can be found like this.

648:2x 2x 2x 3x 3x 3x 3

904:2x 2x 2x 113

678:2x 3x 113

259:7x 37

391:17x 23

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 3x 113 = 5424

Therefore, the value for common factors is 5424.

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 = 40220702492544/(1x5424)

LCM = 40220702492544/5424

LCM = 7415321256

Thus, we can understand that the LCM of 648,904,678,259,391 is 7415321256.
