Given numbers are 642,807,752,923

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

The LCM of 642,807,752,923 is 59934495504.

Find LCM of 642,807,752,923 with Prime Factorization

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

2 x 3 x 107 x 269 x 376 x 923 = 59934495504

Therefore, the lowest common multiple of 642,807,752,923 is 59934495504.

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 807 x 752 x 923 = 359606973024

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

807 : 1, 3, 269, 807

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

923 : 1, 13, 71, 923

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,807,752,923, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

807:3x 269

752:2x 2x 2x 2x 47

923:13x 71

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 359606973024/(1x6)

LCM = 359606973024/6

LCM = 59934495504

Thus, we can understand that the LCM of 642,807,752,923 is 59934495504.
