Given numbers are 445,781,917,968,391

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

The LCM of 445,781,917,968,391 is 10965787106120.

Find LCM of 445,781,917,968,391 with Prime Factorization

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

11 x 445 x 71 x 917 x 88 x 391 = 10965787106120

Therefore, the lowest common multiple of 445,781,917,968,391 is 10965787106120.

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.

445 x 781 x 917 x 968 x 391 = 120623658167320

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.

445 : 1, 5, 89, 445

781 : 1, 11, 71, 781

917 : 1, 7, 131, 917

968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,781,917,968,391, is 1.

Now, the common factors can be found like this.

445:5x 89

781:11x 71

917:7x 131

968:2x 2x 2x 11x 11

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.

11 = 11

Therefore, the value for common factors is 11.

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 = 120623658167320/(1x11)

LCM = 120623658167320/11

LCM = 10965787106120

Thus, we can understand that the LCM of 445,781,917,968,391 is 10965787106120.
