Given numbers are 438,605,825,720,291

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

The LCM of 438,605,825,720,291 is 3084483600.

Find LCM of 438,605,825,720,291 with Prime Factorization

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

2 x 3 x 5 x 11 x 73 x 11 x 5 x 24 x 97 = 3084483600

Therefore, the lowest common multiple of 438,605,825,720,291 is 3084483600.

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.

438 x 605 x 825 x 720 x 291 = 45804581460000

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.

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

605 : 1, 5, 11, 55, 121, 605

825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

291 : 1, 3, 97, 291

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,605,825,720,291, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

605:5x 11x 11

825:3x 5x 5x 11

720:2x 2x 2x 2x 3x 3x 5

291:3x 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 3x 3x 3x 5x 5x 11 = 14850

Therefore, the value for common factors is 14850.

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 = 45804581460000/(1x14850)

LCM = 45804581460000/14850

LCM = 3084483600

Thus, we can understand that the LCM of 438,605,825,720,291 is 3084483600.
