Given numbers are 388,272,271,844,690

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

The LCM of 388,272,271,844,690 is 520488908880.

Find LCM of 388,272,271,844,690 with Prime Factorization

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

2 x 2 x 97 x 68 x 271 x 211 x 345 = 520488908880

Therefore, the lowest common multiple of 388,272,271,844,690 is 520488908880.

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 272 x 271 x 844 x 690 = 16655645084160

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

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

271 : 1, 271

844 : 1, 2, 4, 211, 422, 844

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,272,271,844,690, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

272:2x 2x 2x 2x 17

271:271

844:2x 2x 211

690:2x 3x 5x 23

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 2x 2x 2 = 32

Therefore, the value for common factors is 32.

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 = 16655645084160/(1x32)

LCM = 16655645084160/32

LCM = 520488908880

Thus, we can understand that the LCM of 388,272,271,844,690 is 520488908880.
