Given numbers are 455,278,382,561

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

The LCM of 455,278,382,561 is 13553529990.

Find LCM of 455,278,382,561 with Prime Factorization

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

2 x 455 x 139 x 191 x 561 = 13553529990

Therefore, the lowest common multiple of 455,278,382,561 is 13553529990.

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.

455 x 278 x 382 x 561 = 27107059980

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.

455 : 1, 5, 7, 13, 35, 65, 91, 455

278 : 1, 2, 139, 278

382 : 1, 2, 191, 382

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,278,382,561, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

278:2x 139

382:2x 191

561:3x 11x 17

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

2 = 2

Therefore, the value for common factors is 2.

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 = 27107059980/(1x2)

LCM = 27107059980/2

LCM = 13553529990

Thus, we can understand that the LCM of 455,278,382,561 is 13553529990.
