Given numbers are 247,643,370,556

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

The LCM of 247,643,370,556 is 16336328060.

Find LCM of 247,643,370,556 with Prime Factorization

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

2 x 247 x 643 x 185 x 278 = 16336328060

Therefore, the lowest common multiple of 247,643,370,556 is 16336328060.

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.

247 x 643 x 370 x 556 = 32672656120

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.

247 : 1, 13, 19, 247

643 : 1, 643

370 : 1, 2, 5, 10, 37, 74, 185, 370

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 247,643,370,556, is 1.

Now, the common factors can be found like this.

247:13x 19

643:643

370:2x 5x 37

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 32672656120/(1x2)

LCM = 32672656120/2

LCM = 16336328060

Thus, we can understand that the LCM of 247,643,370,556 is 16336328060.
