Given numbers are 128,628,283,534,407

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

The LCM of 128,628,283,534,407 is 618018859392.

Find LCM of 128,628,283,534,407 with Prime Factorization

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

2 x 2 x 32 x 157 x 283 x 267 x 407 = 618018859392

Therefore, the lowest common multiple of 128,628,283,534,407 is 618018859392.

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 628 x 283 x 534 x 407 = 4944150875136

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

628 : 1, 2, 4, 157, 314, 628

283 : 1, 283

534 : 1, 2, 3, 6, 89, 178, 267, 534

407 : 1, 11, 37, 407

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,628,283,534,407, is 1.

Now, the common factors can be found like this.

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

628:2x 2x 157

283:283

534:2x 3x 89

407:11x 37

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 2 = 8

Therefore, the value for common factors is 8.

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 = 4944150875136/(1x8)

LCM = 4944150875136/8

LCM = 618018859392

Thus, we can understand that the LCM of 128,628,283,534,407 is 618018859392.
