Given numbers are 254,391,391,225

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

The LCM of 254,391,391,225 is 22345650.

Find LCM of 254,391,391,225 with Prime Factorization

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

17 x 23 x 254 x 1 x 1 x 225 = 22345650

Therefore, the lowest common multiple of 254,391,391,225 is 22345650.

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 391 x 391 x 225 = 8737149150

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

391 : 1, 17, 23, 391

391 : 1, 17, 23, 391

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,391,391,225, is 1.

Now, the common factors can be found like this.

254:2x 127

391:17x 23

391:17x 23

225:3x 3x 5x 5

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

17x 23 = 391

Therefore, the value for common factors is 391.

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 = 8737149150/(1x391)

LCM = 8737149150/391

LCM = 22345650

Thus, we can understand that the LCM of 254,391,391,225 is 22345650.
