Given numbers are 445,466,731,780

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

The LCM of 445,466,731,780 is 11823822660.

Find LCM of 445,466,731,780 with Prime Factorization

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

2 x 5 x 89 x 233 x 731 x 78 = 11823822660

Therefore, the lowest common multiple of 445,466,731,780 is 11823822660.

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.

445 x 466 x 731 x 780 = 118238226600

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.

445 : 1, 5, 89, 445

466 : 1, 2, 233, 466

731 : 1, 17, 43, 731

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,466,731,780, is 1.

Now, the common factors can be found like this.

445:5x 89

466:2x 233

731:17x 43

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 5 = 10

Therefore, the value for common factors is 10.

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 = 118238226600/(1x10)

LCM = 118238226600/10

LCM = 11823822660

Thus, we can understand that the LCM of 445,466,731,780 is 11823822660.
