Given numbers are 494,172,781,430,903

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

The LCM of 494,172,781,430,903 is 3483900420.

Find LCM of 494,172,781,430,903 with Prime Factorization

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

2 x 43 x 247 x 2 x 781 x 5 x 21 = 3483900420

Therefore, the lowest common multiple of 494,172,781,430,903 is 3483900420.

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.

494 x 172 x 781 x 430 x 903 = 25766927506320

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.

494 : 1, 2, 13, 19, 26, 38, 247, 494

172 : 1, 2, 4, 43, 86, 172

781 : 1, 11, 71, 781

430 : 1, 2, 5, 10, 43, 86, 215, 430

903 : 1, 3, 7, 21, 43, 129, 301, 903

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,172,781,430,903, is 1.

Now, the common factors can be found like this.

494:2x 13x 19

172:2x 2x 43

781:11x 71

430:2x 5x 43

903:3x 7x 43

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

2x 2x 43x 43 = 7396

Therefore, the value for common factors is 7396.

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 = 25766927506320/(1x7396)

LCM = 25766927506320/7396

LCM = 3483900420

Thus, we can understand that the LCM of 494,172,781,430,903 is 3483900420.
