Given numbers are 628,439,128,658

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

The LCM of 628,439,128,658 is 2902485376.

Find LCM of 628,439,128,658 with Prime Factorization

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

2 x 2 x 157 x 439 x 32 x 329 = 2902485376

Therefore, the lowest common multiple of 628,439,128,658 is 2902485376.

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.

628 x 439 x 128 x 658 = 23219883008

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.

628 : 1, 2, 4, 157, 314, 628

439 : 1, 439

128 : 1, 2, 4, 8, 16, 32, 64, 128

658 : 1, 2, 7, 14, 47, 94, 329, 658

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,439,128,658, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

439:439

128:2x 2x 2x 2x 2x 2x 2

658:2x 7x 47

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 23219883008/(1x8)

LCM = 23219883008/8

LCM = 2902485376

Thus, we can understand that the LCM of 628,439,128,658 is 2902485376.
