Given numbers are 425,819,793,991

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

The LCM of 425,819,793,991 is 21041481825.

Find LCM of 425,819,793,991 with Prime Factorization

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

13 x 425 x 63 x 61 x 991 = 21041481825

Therefore, the lowest common multiple of 425,819,793,991 is 21041481825.

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.

425 x 819 x 793 x 991 = 273539263725

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.

425 : 1, 5, 17, 25, 85, 425

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

793 : 1, 13, 61, 793

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 425,819,793,991, is 1.

Now, the common factors can be found like this.

425:5x 5x 17

819:3x 3x 7x 13

793:13x 61

991:991

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

13 = 13

Therefore, the value for common factors is 13.

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 = 273539263725/(1x13)

LCM = 273539263725/13

LCM = 21041481825

Thus, we can understand that the LCM of 425,819,793,991 is 21041481825.
