Given numbers are 189,920,570,780

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

The LCM of 189,920,570,780 is 42948360.

Find LCM of 189,920,570,780 with Prime Factorization

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

2 x 2 x 3 x 5 x 63 x 46 x 19 x 13 = 42948360

Therefore, the lowest common multiple of 189,920,570,780 is 42948360.

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.

189 x 920 x 570 x 780 = 77307048000

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.

189 : 1, 3, 7, 9, 21, 27, 63, 189

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

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

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 189,920,570,780, is 1.

Now, the common factors can be found like this.

189:3x 3x 3x 7

920:2x 2x 2x 5x 23

570:2x 3x 5x 19

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 2x 2x 3x 3x 5x 5 = 1800

Therefore, the value for common factors is 1800.

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 = 77307048000/(1x1800)

LCM = 77307048000/1800

LCM = 42948360

Thus, we can understand that the LCM of 189,920,570,780 is 42948360.
