Given numbers are 803,473,128,891

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

The LCM of 803,473,128,891 is 357996672.

Find LCM of 803,473,128,891 with Prime Factorization

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

11 x 73 x 43 x 128 x 81 = 357996672

Therefore, the lowest common multiple of 803,473,128,891 is 357996672.

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.

803 x 473 x 128 x 891 = 43317597312

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.

803 : 1, 11, 73, 803

473 : 1, 11, 43, 473

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

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,473,128,891, is 1.

Now, the common factors can be found like this.

803:11x 73

473:11x 43

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

891:3x 3x 3x 3x 11

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 43317597312/(1x121)

LCM = 43317597312/121

LCM = 357996672

Thus, we can understand that the LCM of 803,473,128,891 is 357996672.
