Given numbers are 447,381,621,985,780

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

The LCM of 447,381,621,985,780 is 601895593260.

Find LCM of 447,381,621,985,780 with Prime Factorization

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

3 x 5 x 149 x 127 x 207 x 197 x 52 = 601895593260

Therefore, the lowest common multiple of 447,381,621,985,780 is 601895593260.

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.

447 x 381 x 621 x 985 x 780 = 81255905090100

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.

447 : 1, 3, 149, 447

381 : 1, 3, 127, 381

621 : 1, 3, 9, 23, 27, 69, 207, 621

985 : 1, 5, 197, 985

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 447,381,621,985,780, is 1.

Now, the common factors can be found like this.

447:3x 149

381:3x 127

621:3x 3x 3x 23

985:5x 197

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.

3x 3x 3x 5 = 135

Therefore, the value for common factors is 135.

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 = 81255905090100/(1x135)

LCM = 81255905090100/135

LCM = 601895593260

Thus, we can understand that the LCM of 447,381,621,985,780 is 601895593260.
