Given numbers are 455,299,219,821

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

The LCM of 455,299,219,821 is 1881596535.

Find LCM of 455,299,219,821 with Prime Factorization

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

13 x 35 x 23 x 219 x 821 = 1881596535

Therefore, the lowest common multiple of 455,299,219,821 is 1881596535.

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 299 x 219 x 821 = 24460754955

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

299 : 1, 13, 23, 299

219 : 1, 3, 73, 219

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,299,219,821, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

299:13x 23

219:3x 73

821:821

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

13 = 13

Therefore, the value for common factors is 13.

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 = 24460754955/(1x13)

LCM = 24460754955/13

LCM = 1881596535

Thus, we can understand that the LCM of 455,299,219,821 is 1881596535.
