Given numbers are 388,378,346,253,863

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

The LCM of 388,378,346,253,863 is 2769943749804.

Find LCM of 388,378,346,253,863 with Prime Factorization

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

2 x 194 x 189 x 173 x 253 x 863 = 2769943749804

Therefore, the lowest common multiple of 388,378,346,253,863 is 2769943749804.

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.

388 x 378 x 346 x 253 x 863 = 11079774999216

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.

388 : 1, 2, 4, 97, 194, 388

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

346 : 1, 2, 173, 346

253 : 1, 11, 23, 253

863 : 1, 863

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,378,346,253,863, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

378:2x 3x 3x 3x 7

346:2x 173

253:11x 23

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 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 = 11079774999216/(1x4)

LCM = 11079774999216/4

LCM = 2769943749804

Thus, we can understand that the LCM of 388,378,346,253,863 is 2769943749804.
