Given numbers are 478,663,432,728,424

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

The LCM of 478,663,432,728,424 is 8465406768.

Find LCM of 478,663,432,728,424 with Prime Factorization

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

2 x 2 x 2 x 3 x 13 x 239 x 17 x 18 x 7 x 53 = 8465406768

Therefore, the lowest common multiple of 478,663,432,728,424 is 8465406768.

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.

478 x 663 x 432 x 728 x 424 = 42259310585856

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.

478 : 1, 2, 239, 478

663 : 1, 3, 13, 17, 39, 51, 221, 663

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

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 478,663,432,728,424, is 1.

Now, the common factors can be found like this.

478:2x 239

663:3x 13x 17

432:2x 2x 2x 2x 3x 3x 3

728:2x 2x 2x 7x 13

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 3x 13 = 4992

Therefore, the value for common factors is 4992.

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 = 42259310585856/(1x4992)

LCM = 42259310585856/4992

LCM = 8465406768

Thus, we can understand that the LCM of 478,663,432,728,424 is 8465406768.
