Given numbers are 855,103,987,946,447

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

The LCM of 855,103,987,946,447 is 4083914509290.

Find LCM of 855,103,987,946,447 with Prime Factorization

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

3 x 285 x 103 x 329 x 946 x 149 = 4083914509290

Therefore, the lowest common multiple of 855,103,987,946,447 is 4083914509290.

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.

855 x 103 x 987 x 946 x 447 = 36755230583610

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.

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

103 : 1, 103

987 : 1, 3, 7, 21, 47, 141, 329, 987

946 : 1, 2, 11, 22, 43, 86, 473, 946

447 : 1, 3, 149, 447

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,103,987,946,447, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

103:103

987:3x 7x 47

946:2x 11x 43

447:3x 149

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 36755230583610/(1x9)

LCM = 36755230583610/9

LCM = 4083914509290

Thus, we can understand that the LCM of 855,103,987,946,447 is 4083914509290.
