Given numbers are 254,198,406,331

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

The LCM of 254,198,406,331 is 1689635178.

Find LCM of 254,198,406,331 with Prime Factorization

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

2 x 127 x 99 x 203 x 331 = 1689635178

Therefore, the lowest common multiple of 254,198,406,331 is 1689635178.

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.

254 x 198 x 406 x 331 = 6758540712

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.

254 : 1, 2, 127, 254

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

406 : 1, 2, 7, 14, 29, 58, 203, 406

331 : 1, 331

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,198,406,331, is 1.

Now, the common factors can be found like this.

254:2x 127

198:2x 3x 3x 11

406:2x 7x 29

331:331

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 = 6758540712/(1x4)

LCM = 6758540712/4

LCM = 1689635178

Thus, we can understand that the LCM of 254,198,406,331 is 1689635178.
