Given numbers are 655,345,759,444,990

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

The LCM of 655,345,759,444,990 is 220732380.

Find LCM of 655,345,759,444,990 with Prime Factorization

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

2 x 3 x 5 x 11 x 23 x 131 x 1 x 1 x 74 x 3 = 220732380

Therefore, the lowest common multiple of 655,345,759,444,990 is 220732380.

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.

655 x 345 x 759 x 444 x 990 = 75391144389000

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.

655 : 1, 5, 131, 655

345 : 1, 3, 5, 15, 23, 69, 115, 345

759 : 1, 3, 11, 23, 33, 69, 253, 759

444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,345,759,444,990, is 1.

Now, the common factors can be found like this.

655:5x 131

345:3x 5x 23

759:3x 11x 23

444:2x 2x 3x 37

990:2x 3x 3x 5x 11

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 11x 23 = 341550

Therefore, the value for common factors is 341550.

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 = 75391144389000/(1x341550)

LCM = 75391144389000/341550

LCM = 220732380

Thus, we can understand that the LCM of 655,345,759,444,990 is 220732380.
