Given numbers are 389,394,782,694

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

The LCM of 389,394,782,694 is 20794671082.

Find LCM of 389,394,782,694 with Prime Factorization

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

2 x 389 x 197 x 391 x 347 = 20794671082

Therefore, the lowest common multiple of 389,394,782,694 is 20794671082.

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.

389 x 394 x 782 x 694 = 83178684328

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.

389 : 1, 389

394 : 1, 2, 197, 394

782 : 1, 2, 17, 23, 34, 46, 391, 782

694 : 1, 2, 347, 694

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,394,782,694, is 1.

Now, the common factors can be found like this.

389:389

394:2x 197

782:2x 17x 23

694:2x 347

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 = 83178684328/(1x4)

LCM = 83178684328/4

LCM = 20794671082

Thus, we can understand that the LCM of 389,394,782,694 is 20794671082.
