Given numbers are 399,389,437,995

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

The LCM of 399,389,437,995 is 3552003735.

Find LCM of 399,389,437,995 with Prime Factorization

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

19 x 21 x 389 x 23 x 995 = 3552003735

Therefore, the lowest common multiple of 399,389,437,995 is 3552003735.

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 389 x 437 x 995 = 67488070965

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

389 : 1, 389

437 : 1, 19, 23, 437

995 : 1, 5, 199, 995

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,389,437,995, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

389:389

437:19x 23

995:5x 199

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

19 = 19

Therefore, the value for common factors is 19.

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 = 67488070965/(1x19)

LCM = 67488070965/19

LCM = 3552003735

Thus, we can understand that the LCM of 399,389,437,995 is 3552003735.
