Given numbers are 634,389,407,728

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

The LCM of 634,389,407,728 is 36537148648.

Find LCM of 634,389,407,728 with Prime Factorization

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

2 x 317 x 389 x 407 x 364 = 36537148648

Therefore, the lowest common multiple of 634,389,407,728 is 36537148648.

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.

634 x 389 x 407 x 728 = 73074297296

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.

634 : 1, 2, 317, 634

389 : 1, 389

407 : 1, 11, 37, 407

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,389,407,728, is 1.

Now, the common factors can be found like this.

634:2x 317

389:389

407:11x 37

728:2x 2x 2x 7x 13

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 = 73074297296/(1x2)

LCM = 73074297296/2

LCM = 36537148648

Thus, we can understand that the LCM of 634,389,407,728 is 36537148648.
