Given numbers are 306,242,447,785,780

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

The LCM of 306,242,447,785,780 is 112599398340.

Find LCM of 306,242,447,785,780 with Prime Factorization

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

2 x 3 x 5 x 51 x 121 x 149 x 157 x 26 = 112599398340

Therefore, the lowest common multiple of 306,242,447,785,780 is 112599398340.

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.

306 x 242 x 447 x 785 x 780 = 20267891701200

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.

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

242 : 1, 2, 11, 22, 121, 242

447 : 1, 3, 149, 447

785 : 1, 5, 157, 785

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 306,242,447,785,780, is 1.

Now, the common factors can be found like this.

306:2x 3x 3x 17

242:2x 11x 11

447:3x 149

785:5x 157

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 3x 3x 5 = 180

Therefore, the value for common factors is 180.

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 = 20267891701200/(1x180)

LCM = 20267891701200/180

LCM = 112599398340

Thus, we can understand that the LCM of 306,242,447,785,780 is 112599398340.
