Given numbers are 455,805,798,661,919

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

The LCM of 455,805,798,661,919 is 724704661590.

Find LCM of 455,805,798,661,919 with Prime Factorization

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

5 x 7 x 13 x 23 x 114 x 661 x 919 = 724704661590

Therefore, the lowest common multiple of 455,805,798,661,919 is 724704661590.

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.

455 x 805 x 798 x 661 x 919 = 177552642089550

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.

455 : 1, 5, 7, 13, 35, 65, 91, 455

805 : 1, 5, 7, 23, 35, 115, 161, 805

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

661 : 1, 661

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,805,798,661,919, is 1.

Now, the common factors can be found like this.

455:5x 7x 13

805:5x 7x 23

798:2x 3x 7x 19

661:661

919:919

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

5x 7x 7 = 245

Therefore, the value for common factors is 245.

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 = 177552642089550/(1x245)

LCM = 177552642089550/245

LCM = 724704661590

Thus, we can understand that the LCM of 455,805,798,661,919 is 724704661590.
