Given numbers are 642,766,652,145

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

The LCM of 642,766,652,145 is 11623031220.

Find LCM of 642,766,652,145 with Prime Factorization

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

2 x 321 x 383 x 326 x 145 = 11623031220

Therefore, the lowest common multiple of 642,766,652,145 is 11623031220.

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 766 x 652 x 145 = 46492124880

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

766 : 1, 2, 383, 766

652 : 1, 2, 4, 163, 326, 652

145 : 1, 5, 29, 145

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,766,652,145, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

766:2x 383

652:2x 2x 163

145:5x 29

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 = 46492124880/(1x4)

LCM = 46492124880/4

LCM = 11623031220

Thus, we can understand that the LCM of 642,766,652,145 is 11623031220.
