Given numbers are 388,253,520,279

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

The LCM of 388,253,520,279 is 3560408280.

Find LCM of 388,253,520,279 with Prime Factorization

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

2 x 2 x 97 x 253 x 130 x 279 = 3560408280

Therefore, the lowest common multiple of 388,253,520,279 is 3560408280.

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 253 x 520 x 279 = 14241633120

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

253 : 1, 11, 23, 253

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

279 : 1, 3, 9, 31, 93, 279

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,253,520,279, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

253:11x 23

520:2x 2x 2x 5x 13

279:3x 3x 31

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 = 14241633120/(1x4)

LCM = 14241633120/4

LCM = 3560408280

Thus, we can understand that the LCM of 388,253,520,279 is 3560408280.
