Given numbers are 878,985,394,638

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

The LCM of 878,985,394,638 is 275880770.

Find LCM of 878,985,394,638 with Prime Factorization

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

2 x 197 x 439 x 5 x 1 x 319 = 275880770

Therefore, the lowest common multiple of 878,985,394,638 is 275880770.

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.

878 x 985 x 394 x 638 = 217394046760

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.

878 : 1, 2, 439, 878

985 : 1, 5, 197, 985

394 : 1, 2, 197, 394

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 878,985,394,638, is 1.

Now, the common factors can be found like this.

878:2x 439

985:5x 197

394:2x 197

638:2x 11x 29

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 = 217394046760/(1x788)

LCM = 217394046760/788

LCM = 275880770

Thus, we can understand that the LCM of 878,985,394,638 is 275880770.
