Given numbers are 561,617,788,130

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

The LCM of 561,617,788,130 is 17729137140.

Find LCM of 561,617,788,130 with Prime Factorization

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

2 x 561 x 617 x 394 x 65 = 17729137140

Therefore, the lowest common multiple of 561,617,788,130 is 17729137140.

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.

561 x 617 x 788 x 130 = 35458274280

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

617 : 1, 617

788 : 1, 2, 4, 197, 394, 788

130 : 1, 2, 5, 10, 13, 26, 65, 130

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,617,788,130, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

617:617

788:2x 2x 197

130:2x 5x 13

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 = 35458274280/(1x2)

LCM = 35458274280/2

LCM = 17729137140

Thus, we can understand that the LCM of 561,617,788,130 is 17729137140.
