Given numbers are 128,121,803,605,651

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

The LCM of 128,121,803,605,651 is 3680181120.

Find LCM of 128,121,803,605,651 with Prime Factorization

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

11 x 11 x 128 x 1 x 73 x 5 x 651 = 3680181120

Therefore, the lowest common multiple of 128,121,803,605,651 is 3680181120.

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 121 x 803 x 605 x 651 = 4898321070720

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

121 : 1, 11, 121

803 : 1, 11, 73, 803

605 : 1, 5, 11, 55, 121, 605

651 : 1, 3, 7, 21, 31, 93, 217, 651

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,121,803,605,651, is 1.

Now, the common factors can be found like this.

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

121:11x 11

803:11x 73

605:5x 11x 11

651:3x 7x 31

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

11x 11x 11 = 1331

Therefore, the value for common factors is 1331.

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 = 4898321070720/(1x1331)

LCM = 4898321070720/1331

LCM = 3680181120

Thus, we can understand that the LCM of 128,121,803,605,651 is 3680181120.
