Given numbers are 277,298,990,320

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

The LCM of 277,298,990,320 is 1307528640.

Find LCM of 277,298,990,320 with Prime Factorization

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

2 x 5 x 277 x 149 x 99 x 32 = 1307528640

Therefore, the lowest common multiple of 277,298,990,320 is 1307528640.

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.

277 x 298 x 990 x 320 = 26150572800

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.

277 : 1, 277

298 : 1, 2, 149, 298

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 277,298,990,320, is 1.

Now, the common factors can be found like this.

277:277

298:2x 149

990:2x 3x 3x 5x 11

320:2x 2x 2x 2x 2x 2x 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 5 = 20

Therefore, the value for common factors is 20.

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 = 26150572800/(1x20)

LCM = 26150572800/20

LCM = 1307528640

Thus, we can understand that the LCM of 277,298,990,320 is 1307528640.
