Given numbers are 128,838,939,284

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

The LCM of 128,838,939,284 is 3575591808.

Find LCM of 128,838,939,284 with Prime Factorization

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

2 x 2 x 32 x 419 x 939 x 71 = 3575591808

Therefore, the lowest common multiple of 128,838,939,284 is 3575591808.

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.

128 x 838 x 939 x 284 = 28604734464

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

838 : 1, 2, 419, 838

939 : 1, 3, 313, 939

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,838,939,284, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

838:2x 419

939:3x 313

284:2x 2x 71

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 2 = 8

Therefore, the value for common factors is 8.

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 = 28604734464/(1x8)

LCM = 28604734464/8

LCM = 3575591808

Thus, we can understand that the LCM of 128,838,939,284 is 3575591808.
