Given numbers are 398,847,781,902,584

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

The LCM of 398,847,781,902,584 is 286544145272.

Find LCM of 398,847,781,902,584 with Prime Factorization

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

2 x 11 x 199 x 77 x 71 x 41 x 292 = 286544145272

Therefore, the lowest common multiple of 398,847,781,902,584 is 286544145272.

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.

398 x 847 x 781 x 902 x 584 = 138687366311648

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.

398 : 1, 2, 199, 398

847 : 1, 7, 11, 77, 121, 847

781 : 1, 11, 71, 781

902 : 1, 2, 11, 22, 41, 82, 451, 902

584 : 1, 2, 4, 8, 73, 146, 292, 584

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,847,781,902,584, is 1.

Now, the common factors can be found like this.

398:2x 199

847:7x 11x 11

781:11x 71

902:2x 11x 41

584:2x 2x 2x 73

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 11 = 484

Therefore, the value for common factors is 484.

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 = 138687366311648/(1x484)

LCM = 138687366311648/484

LCM = 286544145272

Thus, we can understand that the LCM of 398,847,781,902,584 is 286544145272.
