Given numbers are 678,206,391,984

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

The LCM of 678,206,391,984 is 4478035416.

Find LCM of 678,206,391,984 with Prime Factorization

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

2 x 3 x 113 x 103 x 391 x 164 = 4478035416

Therefore, the lowest common multiple of 678,206,391,984 is 4478035416.

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 206 x 391 x 984 = 53736424992

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

206 : 1, 2, 103, 206

391 : 1, 17, 23, 391

984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,206,391,984, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

206:2x 103

391:17x 23

984:2x 2x 2x 3x 41

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 3 = 12

Therefore, the value for common factors is 12.

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 = 53736424992/(1x12)

LCM = 53736424992/12

LCM = 4478035416

Thus, we can understand that the LCM of 678,206,391,984 is 4478035416.
