Given numbers are 389,718,422,722

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

The LCM of 389,718,422,722 is 21274712642.

Find LCM of 389,718,422,722 with Prime Factorization

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

2 x 389 x 359 x 211 x 361 = 21274712642

Therefore, the lowest common multiple of 389,718,422,722 is 21274712642.

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.

389 x 718 x 422 x 722 = 85098850568

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.

389 : 1, 389

718 : 1, 2, 359, 718

422 : 1, 2, 211, 422

722 : 1, 2, 19, 38, 361, 722

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,718,422,722, is 1.

Now, the common factors can be found like this.

389:389

718:2x 359

422:2x 211

722:2x 19x 19

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 85098850568/(1x4)

LCM = 85098850568/4

LCM = 21274712642

Thus, we can understand that the LCM of 389,718,422,722 is 21274712642.
