Given numbers are 400,950,388,780

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

The LCM of 400,950,388,780 is 28750800.

Find LCM of 400,950,388,780 with Prime Factorization

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

2 x 2 x 5 x 5 x 4 x 19 x 97 x 39 = 28750800

Therefore, the lowest common multiple of 400,950,388,780 is 28750800.

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.

400 x 950 x 388 x 780 = 115003200000

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.

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950

388 : 1, 2, 4, 97, 194, 388

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,950,388,780, is 2.

Now, the common factors can be found like this.

400:2x 2x 2x 2x 5x 5

950:2x 5x 5x 19

388:2x 2x 97

780:2x 2x 3x 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 5x 5x 5 = 2000

Therefore, the value for common factors is 2000.

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 = 115003200000/(2x2000)

LCM = 115003200000/4000

LCM = 28750800

Thus, we can understand that the LCM of 400,950,388,780 is 28750800.
