Given numbers are 644,568,278,303,556

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

The LCM of 644,568,278,303,556 is 3851515416.

Find LCM of 644,568,278,303,556 with Prime Factorization

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

2 x 2 x 139 x 161 x 142 x 1 x 303 x 1 = 3851515416

Therefore, the lowest common multiple of 644,568,278,303,556 is 3851515416.

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.

644 x 568 x 278 x 303 x 556 = 17131540570368

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

568 : 1, 2, 4, 8, 71, 142, 284, 568

278 : 1, 2, 139, 278

303 : 1, 3, 101, 303

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 644,568,278,303,556, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

568:2x 2x 2x 71

278:2x 139

303:3x 101

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 2x 2x 2x 2x 139 = 4448

Therefore, the value for common factors is 4448.

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 = 17131540570368/(1x4448)

LCM = 17131540570368/4448

LCM = 3851515416

Thus, we can understand that the LCM of 644,568,278,303,556 is 3851515416.
