Given numbers are 394,172,838,438

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

The LCM of 394,172,838,438 is 3109229724.

Find LCM of 394,172,838,438 with Prime Factorization

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

2 x 197 x 86 x 419 x 219 = 3109229724

Therefore, the lowest common multiple of 394,172,838,438 is 3109229724.

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.

394 x 172 x 838 x 438 = 24873837792

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.

394 : 1, 2, 197, 394

172 : 1, 2, 4, 43, 86, 172

838 : 1, 2, 419, 838

438 : 1, 2, 3, 6, 73, 146, 219, 438

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,172,838,438, is 2.

Now, the common factors can be found like this.

394:2x 197

172:2x 2x 43

838:2x 419

438:2x 3x 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 = 24873837792/(2x4)

LCM = 24873837792/8

LCM = 3109229724

Thus, we can understand that the LCM of 394,172,838,438 is 3109229724.
