Given numbers are 644,848,805,552,424

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

The LCM of 644,848,805,552,424 is 2047920.

Find LCM of 644,848,805,552,424 with Prime Factorization

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

2 x 2 x 2 x 7 x 23 x 53 x 1 x 1 x 5 x 3 x 2 = 2047920

Therefore, the lowest common multiple of 644,848,805,552,424 is 2047920.

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 848 x 805 x 552 x 424 = 102892219207680

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

848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848

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

552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552

424 : 1, 2, 4, 8, 53, 106, 212, 424

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,848,805,552,424, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

848:2x 2x 2x 2x 53

805:5x 7x 23

552:2x 2x 2x 3x 23

424:2x 2x 2x 53

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 2x 2x 2x 2x 7x 23x 23x 53 = 50242304

Therefore, the value for common factors is 50242304.

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 = 102892219207680/(1x50242304)

LCM = 102892219207680/50242304

LCM = 2047920

Thus, we can understand that the LCM of 644,848,805,552,424 is 2047920.
