Given numbers are 393,655,509,391

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

The LCM of 393,655,509,391 is 391072335.

Find LCM of 393,655,509,391 with Prime Factorization

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

131 x 3 x 5 x 509 x 391 = 391072335

Therefore, the lowest common multiple of 393,655,509,391 is 391072335.

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 655 x 509 x 391 = 51230475885

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

655 : 1, 5, 131, 655

509 : 1, 509

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,655,509,391, is 1.

Now, the common factors can be found like this.

393:3x 131

655:5x 131

509:509

391:17x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

131 = 131

Therefore, the value for common factors is 131.

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 = 51230475885/(1x131)

LCM = 51230475885/131

LCM = 391072335

Thus, we can understand that the LCM of 393,655,509,391 is 391072335.
