Given numbers are 646,626,752,389

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

The LCM of 646,626,752,389 is 29574288272.

Find LCM of 646,626,752,389 with Prime Factorization

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

2 x 323 x 313 x 376 x 389 = 29574288272

Therefore, the lowest common multiple of 646,626,752,389 is 29574288272.

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.

646 x 626 x 752 x 389 = 118297153088

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

626 : 1, 2, 313, 626

752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752

389 : 1, 389

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,626,752,389, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

626:2x 313

752:2x 2x 2x 2x 47

389:389

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 = 118297153088/(1x4)

LCM = 118297153088/4

LCM = 29574288272

Thus, we can understand that the LCM of 646,626,752,389 is 29574288272.
