Given numbers are 903,497,840,287,798

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

The LCM of 903,497,840,287,798 is 1997761080.

Find LCM of 903,497,840,287,798 with Prime Factorization

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

2 x 3 x 7 x 43 x 71 x 20 x 41 x 19 = 1997761080

Therefore, the lowest common multiple of 903,497,840,287,798 is 1997761080.

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.

903 x 497 x 840 x 287 x 798 = 86339238355440

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.

903 : 1, 3, 7, 21, 43, 129, 301, 903

497 : 1, 7, 71, 497

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

287 : 1, 7, 41, 287

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

7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,497,840,287,798, is 7.

Now, the common factors can be found like this.

903:3x 7x 43

497:7x 71

840:2x 2x 2x 3x 5x 7

287:7x 41

798:2x 3x 7x 19

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

2x 3x 3x 7x 7x 7 = 6174

Therefore, the value for common factors is 6174.

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 = 86339238355440/(7x6174)

LCM = 86339238355440/43218

LCM = 1997761080

Thus, we can understand that the LCM of 903,497,840,287,798 is 1997761080.
