Given numbers are 389,223,778,437,391

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

The LCM of 389,223,778,437,391 is 1288886926.

Find LCM of 389,223,778,437,391 with Prime Factorization

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

23 x 389 x 1 x 223 x 2 x 19 x 17 = 1288886926

Therefore, the lowest common multiple of 389,223,778,437,391 is 1288886926.

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 223 x 778 x 437 x 391 = 11531671326922

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

223 : 1, 223

778 : 1, 2, 389, 778

437 : 1, 19, 23, 437

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,223,778,437,391, is 1.

Now, the common factors can be found like this.

389:389

223:223

778:2x 389

437:19x 23

391:17x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

23x 389 = 8947

Therefore, the value for common factors is 8947.

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 = 11531671326922/(1x8947)

LCM = 11531671326922/8947

LCM = 1288886926

Thus, we can understand that the LCM of 389,223,778,437,391 is 1288886926.
