Given numbers are 535,394,434,642

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

The LCM of 535,394,434,642 is 137224290.

Find LCM of 535,394,434,642 with Prime Factorization

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

2 x 107 x 5 x 197 x 217 x 3 = 137224290

Therefore, the lowest common multiple of 535,394,434,642 is 137224290.

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.

535 x 394 x 434 x 642 = 58731996120

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.

535 : 1, 5, 107, 535

394 : 1, 2, 197, 394

434 : 1, 2, 7, 14, 31, 62, 217, 434

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 535,394,434,642, is 1.

Now, the common factors can be found like this.

535:5x 107

394:2x 197

434:2x 7x 31

642:2x 3x 107

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 107 = 428

Therefore, the value for common factors is 428.

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 = 58731996120/(1x428)

LCM = 58731996120/428

LCM = 137224290

Thus, we can understand that the LCM of 535,394,434,642 is 137224290.
