Given numbers are 356,172,388,778

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

The LCM of 356,172,388,778 is 577616764.

Find LCM of 356,172,388,778 with Prime Factorization

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

2 x 2 x 89 x 43 x 97 x 389 = 577616764

Therefore, the lowest common multiple of 356,172,388,778 is 577616764.

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.

356 x 172 x 388 x 778 = 18483736448

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.

356 : 1, 2, 4, 89, 178, 356

172 : 1, 2, 4, 43, 86, 172

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

778 : 1, 2, 389, 778

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 356,172,388,778, is 2.

Now, the common factors can be found like this.

356:2x 2x 89

172:2x 2x 43

388:2x 2x 97

778:2x 389

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 2 = 16

Therefore, the value for common factors is 16.

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 = 18483736448/(2x16)

LCM = 18483736448/32

LCM = 577616764

Thus, we can understand that the LCM of 356,172,388,778 is 577616764.
