Given numbers are 399,127,215,254

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

The LCM of 399,127,215,254 is 21789390.

Find LCM of 399,127,215,254 with Prime Factorization

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

127 x 399 x 1 x 215 x 2 = 21789390

Therefore, the lowest common multiple of 399,127,215,254 is 21789390.

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.

399 x 127 x 215 x 254 = 2767252530

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.

399 : 1, 3, 7, 19, 21, 57, 133, 399

127 : 1, 127

215 : 1, 5, 43, 215

254 : 1, 2, 127, 254

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,127,215,254, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

127:127

215:5x 43

254:2x 127

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

127 = 127

Therefore, the value for common factors is 127.

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 = 2767252530/(1x127)

LCM = 2767252530/127

LCM = 21789390

Thus, we can understand that the LCM of 399,127,215,254 is 21789390.
