Given numbers are 545,340,731,981,457

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

The LCM of 545,340,731,981,457 is 6554394540.

Find LCM of 545,340,731,981,457 with Prime Factorization

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

5 x 17 x 109 x 1 x 4 x 43 x 9 x 457 = 6554394540

Therefore, the lowest common multiple of 545,340,731,981,457 is 6554394540.

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.

545 x 340 x 731 x 981 x 457 = 60726465413100

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.

545 : 1, 5, 109, 545

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

731 : 1, 17, 43, 731

981 : 1, 3, 9, 109, 327, 981

457 : 1, 457

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,340,731,981,457, is 1.

Now, the common factors can be found like this.

545:5x 109

340:2x 2x 5x 17

731:17x 43

981:3x 3x 109

457:457

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

5x 17x 109 = 9265

Therefore, the value for common factors is 9265.

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 = 60726465413100/(1x9265)

LCM = 60726465413100/9265

LCM = 6554394540

Thus, we can understand that the LCM of 545,340,731,981,457 is 6554394540.
