Given numbers are 128,387,398,509,177

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

The LCM of 128,387,398,509,177 is 296035507584.

Find LCM of 128,387,398,509,177 with Prime Factorization

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

2 x 3 x 64 x 129 x 199 x 509 x 59 = 296035507584

Therefore, the lowest common multiple of 128,387,398,509,177 is 296035507584.

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 387 x 398 x 509 x 177 = 1776213045504

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

387 : 1, 3, 9, 43, 129, 387

398 : 1, 2, 199, 398

509 : 1, 509

177 : 1, 3, 59, 177

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,387,398,509,177, is 1.

Now, the common factors can be found like this.

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

387:3x 3x 43

398:2x 199

509:509

177:3x 59

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 1776213045504/(1x6)

LCM = 1776213045504/6

LCM = 296035507584

Thus, we can understand that the LCM of 128,387,398,509,177 is 296035507584.
