Given numbers are 212,389,778,421

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

The LCM of 212,389,778,421 is 34719028.

Find LCM of 212,389,778,421 with Prime Factorization

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

2 x 389 x 106 x 1 x 1 x 421 = 34719028

Therefore, the lowest common multiple of 212,389,778,421 is 34719028.

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.

212 x 389 x 778 x 421 = 27011403784

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.

212 : 1, 2, 4, 53, 106, 212

389 : 1, 389

778 : 1, 2, 389, 778

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,389,778,421, is 1.

Now, the common factors can be found like this.

212:2x 2x 53

389:389

778:2x 389

421:421

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

2x 389 = 778

Therefore, the value for common factors is 778.

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 = 27011403784/(1x778)

LCM = 27011403784/778

LCM = 34719028

Thus, we can understand that the LCM of 212,389,778,421 is 34719028.
