Given numbers are 455,347,786,556

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

The LCM of 455,347,786,556 is 34499135580.

Find LCM of 455,347,786,556 with Prime Factorization

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

2 x 455 x 347 x 393 x 278 = 34499135580

Therefore, the lowest common multiple of 455,347,786,556 is 34499135580.

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 347 x 786 x 556 = 68998271160

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

347 : 1, 347

786 : 1, 2, 3, 6, 131, 262, 393, 786

556 : 1, 2, 4, 139, 278, 556

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,347,786,556, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

347:347

786:2x 3x 131

556:2x 2x 139

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 = 68998271160/(1x2)

LCM = 68998271160/2

LCM = 34499135580

Thus, we can understand that the LCM of 455,347,786,556 is 34499135580.
