Given numbers are 391,542,847,658

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

The LCM of 391,542,847,658 is 8436402898.

Find LCM of 391,542,847,658 with Prime Factorization

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

2 x 7 x 391 x 271 x 121 x 47 = 8436402898

Therefore, the lowest common multiple of 391,542,847,658 is 8436402898.

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.

391 x 542 x 847 x 658 = 118109640572

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.

391 : 1, 17, 23, 391

542 : 1, 2, 271, 542

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

658 : 1, 2, 7, 14, 47, 94, 329, 658

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,542,847,658, is 1.

Now, the common factors can be found like this.

391:17x 23

542:2x 271

847:7x 11x 11

658:2x 7x 47

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 118109640572/(1x14)

LCM = 118109640572/14

LCM = 8436402898

Thus, we can understand that the LCM of 391,542,847,658 is 8436402898.
