Given numbers are 642,868,457,310

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

The LCM of 642,868,457,310 is 636664980.

Find LCM of 642,868,457,310 with Prime Factorization

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

2 x 31 x 321 x 14 x 457 x 5 = 636664980

Therefore, the lowest common multiple of 642,868,457,310 is 636664980.

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.

642 x 868 x 457 x 310 = 78946457520

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

457 : 1, 457

310 : 1, 2, 5, 10, 31, 62, 155, 310

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,868,457,310, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

868:2x 2x 7x 31

457:457

310:2x 5x 31

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 31 = 124

Therefore, the value for common factors is 124.

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 = 78946457520/(1x124)

LCM = 78946457520/124

LCM = 636664980

Thus, we can understand that the LCM of 642,868,457,310 is 636664980.
