Given numbers are 974,838,394,394

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

The LCM of 974,838,394,394 is 80396882.

Find LCM of 974,838,394,394 with Prime Factorization

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

2 x 197 x 487 x 419 x 1 x 1 = 80396882

Therefore, the lowest common multiple of 974,838,394,394 is 80396882.

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.

974 x 838 x 394 x 394 = 126705486032

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.

974 : 1, 2, 487, 974

838 : 1, 2, 419, 838

394 : 1, 2, 197, 394

394 : 1, 2, 197, 394

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,838,394,394, is 2.

Now, the common factors can be found like this.

974:2x 487

838:2x 419

394:2x 197

394:2x 197

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 197 = 788

Therefore, the value for common factors is 788.

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 = 126705486032/(2x788)

LCM = 126705486032/1576

LCM = 80396882

Thus, we can understand that the LCM of 974,838,394,394 is 80396882.
