Given numbers are 163,731,120,628

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

The LCM of 163,731,120,628 is 2244842520.

Find LCM of 163,731,120,628 with Prime Factorization

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

2 x 2 x 163 x 731 x 30 x 157 = 2244842520

Therefore, the lowest common multiple of 163,731,120,628 is 2244842520.

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.

163 x 731 x 120 x 628 = 8979370080

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.

163 : 1, 163

731 : 1, 17, 43, 731

120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,731,120,628, is 1.

Now, the common factors can be found like this.

163:163

731:17x 43

120:2x 2x 2x 3x 5

628:2x 2x 157

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 8979370080/(1x4)

LCM = 8979370080/4

LCM = 2244842520

Thus, we can understand that the LCM of 163,731,120,628 is 2244842520.
