Given numbers are 728,194,638,485

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

The LCM of 728,194,638,485 is 112632520.

Find LCM of 728,194,638,485 with Prime Factorization

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

2 x 97 x 364 x 1 x 319 x 5 = 112632520

Therefore, the lowest common multiple of 728,194,638,485 is 112632520.

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 194 x 638 x 485 = 43701417760

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

194 : 1, 2, 97, 194

638 : 1, 2, 11, 22, 29, 58, 319, 638

485 : 1, 5, 97, 485

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,194,638,485, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

194:2x 97

638:2x 11x 29

485:5x 97

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 97 = 388

Therefore, the value for common factors is 388.

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 = 43701417760/(1x388)

LCM = 43701417760/388

LCM = 112632520

Thus, we can understand that the LCM of 728,194,638,485 is 112632520.
