Given numbers are 904,889,381,445

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

The LCM of 904,889,381,445 is 1072880760.

Find LCM of 904,889,381,445 with Prime Factorization

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

127 x 904 x 7 x 3 x 445 = 1072880760

Therefore, the lowest common multiple of 904,889,381,445 is 1072880760.

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.

904 x 889 x 381 x 445 = 136255856520

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.

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

889 : 1, 7, 127, 889

381 : 1, 3, 127, 381

445 : 1, 5, 89, 445

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,889,381,445, is 1.

Now, the common factors can be found like this.

904:2x 2x 2x 113

889:7x 127

381:3x 127

445:5x 89

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

127 = 127

Therefore, the value for common factors is 127.

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 = 136255856520/(1x127)

LCM = 136255856520/127

LCM = 1072880760

Thus, we can understand that the LCM of 904,889,381,445 is 1072880760.
