Given numbers are 398,428,642,929

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

The LCM of 398,428,642,929 is 237374364.

Find LCM of 398,428,642,929 with Prime Factorization

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

2 x 107 x 199 x 2 x 3 x 929 = 237374364

Therefore, the lowest common multiple of 398,428,642,929 is 237374364.

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.

398 x 428 x 642 x 929 = 101596227792

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.

398 : 1, 2, 199, 398

428 : 1, 2, 4, 107, 214, 428

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

929 : 1, 929

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,428,642,929, is 1.

Now, the common factors can be found like this.

398:2x 199

428:2x 2x 107

642:2x 3x 107

929:929

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 = 101596227792/(1x428)

LCM = 101596227792/428

LCM = 237374364

Thus, we can understand that the LCM of 398,428,642,929 is 237374364.
