Given numbers are 458,388,921,74

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

The LCM of 458,388,921,74 is 3027809604.

Find LCM of 458,388,921,74 with Prime Factorization

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

2 x 229 x 194 x 921 x 37 = 3027809604

Therefore, the lowest common multiple of 458,388,921,74 is 3027809604.

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.

458 x 388 x 921 x 74 = 12111238416

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.

458 : 1, 2, 229, 458

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

921 : 1, 3, 307, 921

74 : 1, 2, 37, 74

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 458,388,921,74, is 1.

Now, the common factors can be found like this.

458:2x 229

388:2x 2x 97

921:3x 307

74:2x 37

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 12111238416/(1x4)

LCM = 12111238416/4

LCM = 3027809604

Thus, we can understand that the LCM of 458,388,921,74 is 3027809604.
