Given numbers are 819,450,862,978,807

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

The LCM of 819,450,862,978,807 is 773875434150.

Find LCM of 819,450,862,978,807 with Prime Factorization

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

2 x 3 x 3 x 91 x 25 x 431 x 163 x 269 = 773875434150

Therefore, the lowest common multiple of 819,450,862,978,807 is 773875434150.

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.

819 x 450 x 862 x 978 x 807 = 250735640664600

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.

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450

862 : 1, 2, 431, 862

978 : 1, 2, 3, 6, 163, 326, 489, 978

807 : 1, 3, 269, 807

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,450,862,978,807, is 1.

Now, the common factors can be found like this.

819:3x 3x 7x 13

450:2x 3x 3x 5x 5

862:2x 431

978:2x 3x 163

807:3x 269

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 3x 3x 3x 3 = 324

Therefore, the value for common factors is 324.

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 = 250735640664600/(1x324)

LCM = 250735640664600/324

LCM = 773875434150

Thus, we can understand that the LCM of 819,450,862,978,807 is 773875434150.
