Given numbers are 154,873,331,220

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

The LCM of 154,873,331,220 is 445003020.

Find LCM of 154,873,331,220 with Prime Factorization

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

2 x 11 x 7 x 873 x 331 x 10 = 445003020

Therefore, the lowest common multiple of 154,873,331,220 is 445003020.

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.

154 x 873 x 331 x 220 = 9790066440

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.

154 : 1, 2, 7, 11, 14, 22, 77, 154

873 : 1, 3, 9, 97, 291, 873

331 : 1, 331

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,873,331,220, is 1.

Now, the common factors can be found like this.

154:2x 7x 11

873:3x 3x 97

331:331

220:2x 2x 5x 11

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 9790066440/(1x22)

LCM = 9790066440/22

LCM = 445003020

Thus, we can understand that the LCM of 154,873,331,220 is 445003020.
