Given numbers are 920,394,845,139

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

The LCM of 920,394,845,139 is 4257508840.

Find LCM of 920,394,845,139 with Prime Factorization

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

2 x 5 x 92 x 197 x 169 x 139 = 4257508840

Therefore, the lowest common multiple of 920,394,845,139 is 4257508840.

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.

920 x 394 x 845 x 139 = 42575088400

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

394 : 1, 2, 197, 394

845 : 1, 5, 13, 65, 169, 845

139 : 1, 139

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,394,845,139, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

394:2x 197

845:5x 13x 13

139:139

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 42575088400/(1x10)

LCM = 42575088400/10

LCM = 4257508840

Thus, we can understand that the LCM of 920,394,845,139 is 4257508840.
