Given numbers are 855,161,785,192,128

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

The LCM of 855,161,785,192,128 is 2766314880.

Find LCM of 855,161,785,192,128 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 2 x 3 x 5 x 57 x 161 x 157 x 1 x 2 = 2766314880

Therefore, the lowest common multiple of 855,161,785,192,128 is 2766314880.

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 161 x 785 x 192 x 128 = 2655662284800

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

161 : 1, 7, 23, 161

785 : 1, 5, 157, 785

192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192

128 : 1, 2, 4, 8, 16, 32, 64, 128

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,161,785,192,128, is 1.

Now, the common factors can be found like this.

855:3x 3x 5x 19

161:7x 23

785:5x 157

192:2x 2x 2x 2x 2x 2x 3

128:2x 2x 2x 2x 2x 2x 2

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

2x 2x 2x 2x 2x 2x 3x 5 = 960

Therefore, the value for common factors is 960.

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 = 2655662284800/(1x960)

LCM = 2655662284800/960

LCM = 2766314880

Thus, we can understand that the LCM of 855,161,785,192,128 is 2766314880.
