Given numbers are 254,390,419,257

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

The LCM of 254,390,419,257 is 5333538990.

Find LCM of 254,390,419,257 with Prime Factorization

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

2 x 127 x 195 x 419 x 257 = 5333538990

Therefore, the lowest common multiple of 254,390,419,257 is 5333538990.

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 390 x 419 x 257 = 10667077980

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

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

419 : 1, 419

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,390,419,257, is 1.

Now, the common factors can be found like this.

254:2x 127

390:2x 3x 5x 13

419:419

257:257

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

2 = 2

Therefore, the value for common factors is 2.

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 = 10667077980/(1x2)

LCM = 10667077980/2

LCM = 5333538990

Thus, we can understand that the LCM of 254,390,419,257 is 5333538990.
