Given numbers are 790,142,738,407,781

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

The LCM of 790,142,738,407,781 is 8423764470.

Find LCM of 790,142,738,407,781 with Prime Factorization

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

2 x 11 x 71 x 395 x 1 x 369 x 37 x 1 = 8423764470

Therefore, the lowest common multiple of 790,142,738,407,781 is 8423764470.

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.

790 x 142 x 738 x 407 x 781 = 26315840204280

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.

790 : 1, 2, 5, 10, 79, 158, 395, 790

142 : 1, 2, 71, 142

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

407 : 1, 11, 37, 407

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,142,738,407,781, is 1.

Now, the common factors can be found like this.

790:2x 5x 79

142:2x 71

738:2x 3x 3x 41

407:11x 37

781:11x 71

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 11x 71 = 3124

Therefore, the value for common factors is 3124.

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 = 26315840204280/(1x3124)

LCM = 26315840204280/3124

LCM = 8423764470

Thus, we can understand that the LCM of 790,142,738,407,781 is 8423764470.
