Given numbers are 437,802,390,556

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

The LCM of 437,802,390,556 is 18999195540.

Find LCM of 437,802,390,556 with Prime Factorization

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

2 x 437 x 401 x 195 x 278 = 18999195540

Therefore, the lowest common multiple of 437,802,390,556 is 18999195540.

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.

437 x 802 x 390 x 556 = 75996782160

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.

437 : 1, 19, 23, 437

802 : 1, 2, 401, 802

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

556 : 1, 2, 4, 139, 278, 556

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,802,390,556, is 1.

Now, the common factors can be found like this.

437:19x 23

802:2x 401

390:2x 3x 5x 13

556:2x 2x 139

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 = 75996782160/(1x4)

LCM = 75996782160/4

LCM = 18999195540

Thus, we can understand that the LCM of 437,802,390,556 is 18999195540.
