Given numbers are 398,134,663,838

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

The LCM of 398,134,663,838 is 7407734802.

Find LCM of 398,134,663,838 with Prime Factorization

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

2 x 199 x 67 x 663 x 419 = 7407734802

Therefore, the lowest common multiple of 398,134,663,838 is 7407734802.

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 134 x 663 x 838 = 29630939208

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

134 : 1, 2, 67, 134

663 : 1, 3, 13, 17, 39, 51, 221, 663

838 : 1, 2, 419, 838

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,134,663,838, is 1.

Now, the common factors can be found like this.

398:2x 199

134:2x 67

663:3x 13x 17

838:2x 419

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 = 29630939208/(1x4)

LCM = 29630939208/4

LCM = 7407734802

Thus, we can understand that the LCM of 398,134,663,838 is 7407734802.
