Given numbers are 780,556,727,660,975

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

The LCM of 780,556,727,660,975 is 4335173700.

Find LCM of 780,556,727,660,975 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 1 x 139 x 727 x 11 x 5 = 4335173700

Therefore, the lowest common multiple of 780,556,727,660,975 is 4335173700.

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.

780 x 556 x 727 x 660 x 975 = 202886129160000

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.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

556 : 1, 2, 4, 139, 278, 556

727 : 1, 727

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

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,556,727,660,975, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

556:2x 2x 139

727:727

660:2x 2x 3x 5x 11

975:3x 5x 5x 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 3x 3x 5x 5x 13 = 46800

Therefore, the value for common factors is 46800.

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 = 202886129160000/(1x46800)

LCM = 202886129160000/46800

LCM = 4335173700

Thus, we can understand that the LCM of 780,556,727,660,975 is 4335173700.
