Given numbers are 678,133,478,891

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

The LCM of 678,133,478,891 is 6400821042.

Find LCM of 678,133,478,891 with Prime Factorization

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

2 x 3 x 113 x 133 x 239 x 297 = 6400821042

Therefore, the lowest common multiple of 678,133,478,891 is 6400821042.

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.

678 x 133 x 478 x 891 = 38404926252

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

133 : 1, 7, 19, 133

478 : 1, 2, 239, 478

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,133,478,891, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

133:7x 19

478:2x 239

891:3x 3x 3x 3x 11

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 38404926252/(1x6)

LCM = 38404926252/6

LCM = 6400821042

Thus, we can understand that the LCM of 678,133,478,891 is 6400821042.
