Given numbers are 393,621,782,214

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

The LCM of 393,621,782,214 is 295954938.

Find LCM of 393,621,782,214 with Prime Factorization

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

2 x 3 x 23 x 131 x 9 x 17 x 107 = 295954938

Therefore, the lowest common multiple of 393,621,782,214 is 295954938.

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.

393 x 621 x 782 x 214 = 40841781444

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.

393 : 1, 3, 131, 393

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

782 : 1, 2, 17, 23, 34, 46, 391, 782

214 : 1, 2, 107, 214

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,621,782,214, is 1.

Now, the common factors can be found like this.

393:3x 131

621:3x 3x 3x 23

782:2x 17x 23

214:2x 107

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 23 = 138

Therefore, the value for common factors is 138.

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 = 40841781444/(1x138)

LCM = 40841781444/138

LCM = 295954938

Thus, we can understand that the LCM of 393,621,782,214 is 295954938.
