Given numbers are 399,778,389,901

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

The LCM of 399,778,389,901 is 279690222.

Find LCM of 399,778,389,901 with Prime Factorization

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

389 x 399 x 2 x 1 x 901 = 279690222

Therefore, the lowest common multiple of 399,778,389,901 is 279690222.

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 778 x 389 x 901 = 108799496358

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

778 : 1, 2, 389, 778

389 : 1, 389

901 : 1, 17, 53, 901

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,778,389,901, is 1.

Now, the common factors can be found like this.

399:3x 7x 19

778:2x 389

389:389

901:17x 53

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

389 = 389

Therefore, the value for common factors is 389.

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 = 108799496358/(1x389)

LCM = 108799496358/389

LCM = 279690222

Thus, we can understand that the LCM of 399,778,389,901 is 279690222.
