Given numbers are 940,104,390,910,645

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

The LCM of 940,104,390,910,645 is 22069320.

Find LCM of 940,104,390,910,645 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 47 x 2 x 1 x 7 x 43 = 22069320

Therefore, the lowest common multiple of 940,104,390,910,645 is 22069320.

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.

940 x 104 x 390 x 910 x 645 = 22378290480000

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.

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

104 : 1, 2, 4, 8, 13, 26, 52, 104

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

645 : 1, 3, 5, 15, 43, 129, 215, 645

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 940,104,390,910,645, is 1.

Now, the common factors can be found like this.

940:2x 2x 5x 47

104:2x 2x 2x 13

390:2x 3x 5x 13

910:2x 5x 7x 13

645:3x 5x 43

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 2x 2x 3x 5x 5x 5x 13x 13 = 1014000

Therefore, the value for common factors is 1014000.

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 = 22378290480000/(1x1014000)

LCM = 22378290480000/1014000

LCM = 22069320

Thus, we can understand that the LCM of 940,104,390,910,645 is 22069320.
