Given numbers are 644,608,554,437,486

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

The LCM of 644,608,554,437,486 is 6588939168.

Find LCM of 644,608,554,437,486 with Prime Factorization

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

2 x 2 x 19 x 23 x 7 x 8 x 277 x 1 x 243 = 6588939168

Therefore, the lowest common multiple of 644,608,554,437,486 is 6588939168.

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.

644 x 608 x 554 x 437 x 486 = 46069862662656

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608

554 : 1, 2, 277, 554

437 : 1, 19, 23, 437

486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,608,554,437,486, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

608:2x 2x 2x 2x 2x 19

554:2x 277

437:19x 23

486:2x 3x 3x 3x 3x 3

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 19x 23 = 6992

Therefore, the value for common factors is 6992.

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 = 46069862662656/(1x6992)

LCM = 46069862662656/6992

LCM = 6588939168

Thus, we can understand that the LCM of 644,608,554,437,486 is 6588939168.
