Given numbers are 120,438,855,654,850

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

The LCM of 120,438,855,654,850 is 4626199800.

Find LCM of 120,438,855,654,850 with Prime Factorization

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

2 x 3 x 5 x 4 x 73 x 57 x 109 x 85 = 4626199800

Therefore, the lowest common multiple of 120,438,855,654,850 is 4626199800.

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.

120 x 438 x 855 x 654 x 850 = 24981478920000

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.

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

438 : 1, 2, 3, 6, 73, 146, 219, 438

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

654 : 1, 2, 3, 6, 109, 218, 327, 654

850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,438,855,654,850, is 1.

Now, the common factors can be found like this.

120:2x 2x 2x 3x 5

438:2x 3x 73

855:3x 3x 5x 19

654:2x 3x 109

850:2x 5x 5x 17

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 3x 3x 3x 5x 5 = 5400

Therefore, the value for common factors is 5400.

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 = 24981478920000/(1x5400)

LCM = 24981478920000/5400

LCM = 4626199800

Thus, we can understand that the LCM of 120,438,855,654,850 is 4626199800.
