Given numbers are 310,780,803,930

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

The LCM of 310,780,803,930 is 19416540.

Find LCM of 310,780,803,930 with Prime Factorization

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

2 x 3 x 5 x 31 x 1 x 26 x 803 x 1 = 19416540

Therefore, the lowest common multiple of 310,780,803,930 is 19416540.

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.

310 x 780 x 803 x 930 = 180573822000

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.

310 : 1, 2, 5, 10, 31, 62, 155, 310

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

803 : 1, 11, 73, 803

930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,780,803,930, is 1.

Now, the common factors can be found like this.

310:2x 5x 31

780:2x 2x 3x 5x 13

803:11x 73

930:2x 3x 5x 31

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 31 = 9300

Therefore, the value for common factors is 9300.

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 = 180573822000/(1x9300)

LCM = 180573822000/9300

LCM = 19416540

Thus, we can understand that the LCM of 310,780,803,930 is 19416540.
