Given numbers are 399,269,538,305

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

The LCM of 399,269,538,305 is 65471910.

Find LCM of 399,269,538,305 with Prime Factorization

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

269 x 399 x 1 x 2 x 305 = 65471910

Therefore, the lowest common multiple of 399,269,538,305 is 65471910.

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 269 x 538 x 305 = 17611943790

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

269 : 1, 269

538 : 1, 2, 269, 538

305 : 1, 5, 61, 305

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,269,538,305, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

269:269

538:2x 269

305:5x 61

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

269 = 269

Therefore, the value for common factors is 269.

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 = 17611943790/(1x269)

LCM = 17611943790/269

LCM = 65471910

Thus, we can understand that the LCM of 399,269,538,305 is 65471910.
