Given numbers are 622,418,389,639

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

The LCM of 622,418,389,639 is 32313732858.

Find LCM of 622,418,389,639 with Prime Factorization

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

2 x 311 x 209 x 389 x 639 = 32313732858

Therefore, the lowest common multiple of 622,418,389,639 is 32313732858.

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.

622 x 418 x 389 x 639 = 64627465716

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.

622 : 1, 2, 311, 622

418 : 1, 2, 11, 19, 22, 38, 209, 418

389 : 1, 389

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,418,389,639, is 1.

Now, the common factors can be found like this.

622:2x 311

418:2x 11x 19

389:389

639:3x 3x 71

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

2 = 2

Therefore, the value for common factors is 2.

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 = 64627465716/(1x2)

LCM = 64627465716/2

LCM = 32313732858

Thus, we can understand that the LCM of 622,418,389,639 is 32313732858.
