Given numbers are 449,642,577,242,905

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

The LCM of 449,642,577,242,905 is 18213404451330.

Find LCM of 449,642,577,242,905 with Prime Factorization

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

2 x 449 x 321 x 577 x 121 x 905 = 18213404451330

Therefore, the lowest common multiple of 449,642,577,242,905 is 18213404451330.

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.

449 x 642 x 577 x 242 x 905 = 36426808902660

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.

449 : 1, 449

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

577 : 1, 577

242 : 1, 2, 11, 22, 121, 242

905 : 1, 5, 181, 905

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,642,577,242,905, is 1.

Now, the common factors can be found like this.

449:449

642:2x 3x 107

577:577

242:2x 11x 11

905:5x 181

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

2 = 2

Therefore, the value for common factors is 2.

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 = 36426808902660/(1x2)

LCM = 36426808902660/2

LCM = 18213404451330

Thus, we can understand that the LCM of 449,642,577,242,905 is 18213404451330.
