Given numbers are 457,754,198,140

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

The LCM of 457,754,198,140 is 2387925540.

Find LCM of 457,754,198,140 with Prime Factorization

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

2 x 457 x 377 x 99 x 70 = 2387925540

Therefore, the lowest common multiple of 457,754,198,140 is 2387925540.

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.

457 x 754 x 198 x 140 = 9551702160

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.

457 : 1, 457

754 : 1, 2, 13, 26, 29, 58, 377, 754

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 457,754,198,140, is 1.

Now, the common factors can be found like this.

457:457

754:2x 13x 29

198:2x 3x 3x 11

140:2x 2x 5x 7

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 = 9551702160/(1x4)

LCM = 9551702160/4

LCM = 2387925540

Thus, we can understand that the LCM of 457,754,198,140 is 2387925540.
