Given numbers are 398,838,422,146

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

The LCM of 398,838,422,146 is 2568635086.

Find LCM of 398,838,422,146 with Prime Factorization

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

2 x 199 x 419 x 211 x 73 = 2568635086

Therefore, the lowest common multiple of 398,838,422,146 is 2568635086.

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 838 x 422 x 146 = 20549080688

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

838 : 1, 2, 419, 838

422 : 1, 2, 211, 422

146 : 1, 2, 73, 146

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,838,422,146, is 2.

Now, the common factors can be found like this.

398:2x 199

838:2x 419

422:2x 211

146:2x 73

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 20549080688/(2x4)

LCM = 20549080688/8

LCM = 2568635086

Thus, we can understand that the LCM of 398,838,422,146 is 2568635086.
