Given numbers are 307,278,778,430

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

The LCM of 307,278,778,430 is 7137912710.

Find LCM of 307,278,778,430 with Prime Factorization

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

2 x 307 x 139 x 389 x 215 = 7137912710

Therefore, the lowest common multiple of 307,278,778,430 is 7137912710.

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.

307 x 278 x 778 x 430 = 28551650840

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.

307 : 1, 307

278 : 1, 2, 139, 278

778 : 1, 2, 389, 778

430 : 1, 2, 5, 10, 43, 86, 215, 430

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 307,278,778,430, is 1.

Now, the common factors can be found like this.

307:307

278:2x 139

778:2x 389

430:2x 5x 43

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 28551650840/(1x4)

LCM = 28551650840/4

LCM = 7137912710

Thus, we can understand that the LCM of 307,278,778,430 is 7137912710.
