Given numbers are 2,646,399,556

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

The LCM of 2,646,399,556 is 3771348.

Find LCM of 2,646,399,556 with Prime Factorization

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

2 x 19 x 1 x 17 x 21 x 278 = 3771348

Therefore, the lowest common multiple of 2,646,399,556 is 3771348.

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.

2 x 646 x 399 x 556 = 286622448

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.

2 : 1, 2

646 : 1, 2, 17, 19, 34, 38, 323, 646

399 : 1, 3, 7, 19, 21, 57, 133, 399

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 2,646,399,556, is 1.

Now, the common factors can be found like this.

2:2

646:2x 17x 19

399:3x 7x 19

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 19 = 76

Therefore, the value for common factors is 76.

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 = 286622448/(1x76)

LCM = 286622448/76

LCM = 3771348

Thus, we can understand that the LCM of 2,646,399,556 is 3771348.
