Given numbers are 394,978,198,863

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

The LCM of 394,978,198,863 is 5486935014.

Find LCM of 394,978,198,863 with Prime Factorization

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

2 x 3 x 197 x 163 x 33 x 863 = 5486935014

Therefore, the lowest common multiple of 394,978,198,863 is 5486935014.

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.

394 x 978 x 198 x 863 = 65843220168

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.

394 : 1, 2, 197, 394

978 : 1, 2, 3, 6, 163, 326, 489, 978

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

863 : 1, 863

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,978,198,863, is 1.

Now, the common factors can be found like this.

394:2x 197

978:2x 3x 163

198:2x 3x 3x 11

863:863

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 = 65843220168/(1x12)

LCM = 65843220168/12

LCM = 5486935014

Thus, we can understand that the LCM of 394,978,198,863 is 5486935014.
