Given numbers are 639,904,445,791

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

The LCM of 639,904,445,791 is 1799398440.

Find LCM of 639,904,445,791 with Prime Factorization

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

113 x 639 x 8 x 445 x 7 = 1799398440

Therefore, the lowest common multiple of 639,904,445,791 is 1799398440.

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.

639 x 904 x 445 x 791 = 203332023720

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.

639 : 1, 3, 9, 71, 213, 639

904 : 1, 2, 4, 8, 113, 226, 452, 904

445 : 1, 5, 89, 445

791 : 1, 7, 113, 791

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,904,445,791, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

904:2x 2x 2x 113

445:5x 89

791:7x 113

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

113 = 113

Therefore, the value for common factors is 113.

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 = 203332023720/(1x113)

LCM = 203332023720/113

LCM = 1799398440

Thus, we can understand that the LCM of 639,904,445,791 is 1799398440.
