Given numbers are 321,566,153,780

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

The LCM of 321,566,153,780 is 1204578180.

Find LCM of 321,566,153,780 with Prime Factorization

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

2 x 3 x 107 x 283 x 51 x 130 = 1204578180

Therefore, the lowest common multiple of 321,566,153,780 is 1204578180.

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.

321 x 566 x 153 x 780 = 21682407240

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.

321 : 1, 3, 107, 321

566 : 1, 2, 283, 566

153 : 1, 3, 9, 17, 51, 153

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 321,566,153,780, is 1.

Now, the common factors can be found like this.

321:3x 107

566:2x 283

153:3x 3x 17

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 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 21682407240/(1x18)

LCM = 21682407240/18

LCM = 1204578180

Thus, we can understand that the LCM of 321,566,153,780 is 1204578180.
