Given numbers are 619,218,863,921,780

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

The LCM of 619,218,863,921,780 is 13943150684580.

Find LCM of 619,218,863,921,780 with Prime Factorization

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

2 x 3 x 619 x 109 x 863 x 307 x 130 = 13943150684580

Therefore, the lowest common multiple of 619,218,863,921,780 is 13943150684580.

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.

619 x 218 x 863 x 921 x 780 = 83658904107480

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.

619 : 1, 619

218 : 1, 2, 109, 218

863 : 1, 863

921 : 1, 3, 307, 921

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,218,863,921,780, is 1.

Now, the common factors can be found like this.

619:619

218:2x 109

863:863

921:3x 307

780:2x 2x 3x 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.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 83658904107480/(1x6)

LCM = 83658904107480/6

LCM = 13943150684580

Thus, we can understand that the LCM of 619,218,863,921,780 is 13943150684580.
