Given numbers are 505,619,781,920,105

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

The LCM of 505,619,781,920,105 is 943344189480.

Find LCM of 505,619,781,920,105 with Prime Factorization

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

5 x 101 x 619 x 781 x 184 x 21 = 943344189480

Therefore, the lowest common multiple of 505,619,781,920,105 is 943344189480.

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.

505 x 619 x 781 x 920 x 105 = 23583604737000

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.

505 : 1, 5, 101, 505

619 : 1, 619

781 : 1, 11, 71, 781

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

105 : 1, 3, 5, 7, 15, 21, 35, 105

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,619,781,920,105, is 1.

Now, the common factors can be found like this.

505:5x 101

619:619

781:11x 71

920:2x 2x 2x 5x 23

105:3x 5x 7

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 23583604737000/(1x25)

LCM = 23583604737000/25

LCM = 943344189480

Thus, we can understand that the LCM of 505,619,781,920,105 is 943344189480.
