Given numbers are 312,388,521,438

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

The LCM of 312,388,521,438 is 1151030712.

Find LCM of 312,388,521,438 with Prime Factorization

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

2 x 2 x 3 x 26 x 97 x 521 x 73 = 1151030712

Therefore, the lowest common multiple of 312,388,521,438 is 1151030712.

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.

312 x 388 x 521 x 438 = 27624737088

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.

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

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

521 : 1, 521

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,388,521,438, is 1.

Now, the common factors can be found like this.

312:2x 2x 2x 3x 13

388:2x 2x 97

521:521

438:2x 3x 73

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 3 = 24

Therefore, the value for common factors is 24.

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 = 27624737088/(1x24)

LCM = 27624737088/24

LCM = 1151030712

Thus, we can understand that the LCM of 312,388,521,438 is 1151030712.
