Given numbers are 142,284,355,778

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

The LCM of 142,284,355,778 is 552380.

Find LCM of 142,284,355,778 with Prime Factorization

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

2 x 71 x 1 x 2 x 5 x 389 = 552380

Therefore, the lowest common multiple of 142,284,355,778 is 552380.

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.

142 x 284 x 355 x 778 = 11138190320

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.

142 : 1, 2, 71, 142

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

355 : 1, 5, 71, 355

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,284,355,778, is 1.

Now, the common factors can be found like this.

142:2x 71

284:2x 2x 71

355:5x 71

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 71x 71 = 20164

Therefore, the value for common factors is 20164.

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 = 11138190320/(1x20164)

LCM = 11138190320/20164

LCM = 552380

Thus, we can understand that the LCM of 142,284,355,778 is 552380.
