Given numbers are 128,986,177,198,960

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

The LCM of 128,986,177,198,960 is 1842952320.

Find LCM of 128,986,177,198,960 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 2 x 493 x 59 x 33 x 5 = 1842952320

Therefore, the lowest common multiple of 128,986,177,198,960 is 1842952320.

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.

128 x 986 x 177 x 198 x 960 = 4246162145280

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.

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

986 : 1, 2, 17, 29, 34, 58, 493, 986

177 : 1, 3, 59, 177

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,986,177,198,960, is 1.

Now, the common factors can be found like this.

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

986:2x 17x 29

177:3x 59

198:2x 3x 3x 11

960:2x 2x 2x 2x 2x 2x 3x 5

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 2x 2x 3x 3 = 2304

Therefore, the value for common factors is 2304.

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 = 4246162145280/(1x2304)

LCM = 4246162145280/2304

LCM = 1842952320

Thus, we can understand that the LCM of 128,986,177,198,960 is 1842952320.
