Given numbers are 505,458,645,388

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

The LCM of 505,458,645,388 is 5788263540.

Find LCM of 505,458,645,388 with Prime Factorization

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

2 x 5 x 101 x 229 x 129 x 194 = 5788263540

Therefore, the lowest common multiple of 505,458,645,388 is 5788263540.

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.

505 x 458 x 645 x 388 = 57882635400

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.

505 : 1, 5, 101, 505

458 : 1, 2, 229, 458

645 : 1, 3, 5, 15, 43, 129, 215, 645

388 : 1, 2, 4, 97, 194, 388

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,458,645,388, is 1.

Now, the common factors can be found like this.

505:5x 101

458:2x 229

645:3x 5x 43

388:2x 2x 97

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 57882635400/(1x10)

LCM = 57882635400/10

LCM = 5788263540

Thus, we can understand that the LCM of 505,458,645,388 is 5788263540.
