Given numbers are 780,127,845,790,138

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

The LCM of 780,127,845,790,138 is 2339896260.

Find LCM of 780,127,845,790,138 with Prime Factorization

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

2 x 3 x 5 x 13 x 2 x 127 x 13 x 79 x 23 = 2339896260

Therefore, the lowest common multiple of 780,127,845,790,138 is 2339896260.

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.

780 x 127 x 845 x 790 x 138 = 9125595414000

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.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

127 : 1, 127

845 : 1, 5, 13, 65, 169, 845

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,127,845,790,138, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

127:127

845:5x 13x 13

790:2x 5x 79

138:2x 3x 23

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 3x 5x 5x 13 = 3900

Therefore, the value for common factors is 3900.

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 = 9125595414000/(1x3900)

LCM = 9125595414000/3900

LCM = 2339896260

Thus, we can understand that the LCM of 780,127,845,790,138 is 2339896260.
