Given numbers are 660,208,563,728

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

The LCM of 660,208,563,728 is 135255120.

Find LCM of 660,208,563,728 with Prime Factorization

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

2 x 2 x 2 x 13 x 165 x 2 x 563 x 7 = 135255120

Therefore, the lowest common multiple of 660,208,563,728 is 135255120.

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.

660 x 208 x 563 x 728 = 56266129920

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

563 : 1, 563

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,208,563,728, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

208:2x 2x 2x 2x 13

563:563

728:2x 2x 2x 7x 13

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 13 = 416

Therefore, the value for common factors is 416.

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 = 56266129920/(1x416)

LCM = 56266129920/416

LCM = 135255120

Thus, we can understand that the LCM of 660,208,563,728 is 135255120.
