Given numbers are 728,475,128,637,621

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

The LCM of 728,475,128,637,621 is 24051081600.

Find LCM of 728,475,128,637,621 with Prime Factorization

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

2 x 2 x 2 x 7 x 13 x 1 x 475 x 16 x 7 x 621 = 24051081600

Therefore, the lowest common multiple of 728,475,128,637,621 is 24051081600.

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.

728 x 475 x 128 x 637 x 621 = 17509187404800

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.

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

475 : 1, 5, 19, 25, 95, 475

128 : 1, 2, 4, 8, 16, 32, 64, 128

637 : 1, 7, 13, 49, 91, 637

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,475,128,637,621, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

475:5x 5x 19

128:2x 2x 2x 2x 2x 2x 2

637:7x 7x 13

621:3x 3x 3x 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 7x 13 = 728

Therefore, the value for common factors is 728.

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 = 17509187404800/(1x728)

LCM = 17509187404800/728

LCM = 24051081600

Thus, we can understand that the LCM of 728,475,128,637,621 is 24051081600.
