Given numbers are 642,749,449,205

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

The LCM of 642,749,449,205 is 413650230.

Find LCM of 642,749,449,205 with Prime Factorization

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

107 x 6 x 7 x 449 x 205 = 413650230

Therefore, the lowest common multiple of 642,749,449,205 is 413650230.

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 749 x 449 x 205 = 44260574610

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

749 : 1, 7, 107, 749

449 : 1, 449

205 : 1, 5, 41, 205

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,749,449,205, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

749:7x 107

449:449

205:5x 41

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

107 = 107

Therefore, the value for common factors is 107.

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 = 44260574610/(1x107)

LCM = 44260574610/107

LCM = 413650230

Thus, we can understand that the LCM of 642,749,449,205 is 413650230.
