Given numbers are 455,481,247,452

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

The LCM of 455,481,247,452 is 144578980.

Find LCM of 455,481,247,452 with Prime Factorization

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

13 x 35 x 37 x 19 x 452 = 144578980

Therefore, the lowest common multiple of 455,481,247,452 is 144578980.

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 481 x 247 x 452 = 24433847620

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

481 : 1, 13, 37, 481

247 : 1, 13, 19, 247

452 : 1, 2, 4, 113, 226, 452

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,481,247,452, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

481:13x 37

247:13x 19

452:2x 2x 113

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 24433847620/(1x169)

LCM = 24433847620/169

LCM = 144578980

Thus, we can understand that the LCM of 455,481,247,452 is 144578980.
