Given numbers are 666,449,814,920

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

The LCM of 666,449,814,920 is 1513112040.

Find LCM of 666,449,814,920 with Prime Factorization

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

2 x 37 x 9 x 449 x 11 x 460 = 1513112040

Therefore, the lowest common multiple of 666,449,814,920 is 1513112040.

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.

666 x 449 x 814 x 920 = 223940581920

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.

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

449 : 1, 449

814 : 1, 2, 11, 22, 37, 74, 407, 814

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 666,449,814,920, is 1.

Now, the common factors can be found like this.

666:2x 3x 3x 37

449:449

814:2x 11x 37

920:2x 2x 2x 5x 23

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 37 = 148

Therefore, the value for common factors is 148.

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 = 223940581920/(1x148)

LCM = 223940581920/148

LCM = 1513112040

Thus, we can understand that the LCM of 666,449,814,920 is 1513112040.
