Given numbers are 291,139,406,641,904

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

The LCM of 291,139,406,641,904 is 4758064085208.

Find LCM of 291,139,406,641,904 with Prime Factorization

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

2 x 291 x 139 x 203 x 641 x 452 = 4758064085208

Therefore, the lowest common multiple of 291,139,406,641,904 is 4758064085208.

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.

291 x 139 x 406 x 641 x 904 = 9516128170416

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.

291 : 1, 3, 97, 291

139 : 1, 139

406 : 1, 2, 7, 14, 29, 58, 203, 406

641 : 1, 641

904 : 1, 2, 4, 8, 113, 226, 452, 904

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,139,406,641,904, is 1.

Now, the common factors can be found like this.

291:3x 97

139:139

406:2x 7x 29

641:641

904:2x 2x 2x 113

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

2 = 2

Therefore, the value for common factors is 2.

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 = 9516128170416/(1x2)

LCM = 9516128170416/2

LCM = 4758064085208

Thus, we can understand that the LCM of 291,139,406,641,904 is 4758064085208.
