Given numbers are 545,642,263,872

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

The LCM of 545,642,263,872 is 368084280.

Find LCM of 545,642,263,872 with Prime Factorization

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

2 x 109 x 5 x 321 x 263 x 4 = 368084280

Therefore, the lowest common multiple of 545,642,263,872 is 368084280.

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.

545 x 642 x 263 x 872 = 80242373040

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.

545 : 1, 5, 109, 545

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

263 : 1, 263

872 : 1, 2, 4, 8, 109, 218, 436, 872

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,642,263,872, is 1.

Now, the common factors can be found like this.

545:5x 109

642:2x 3x 107

263:263

872:2x 2x 2x 109

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

2x 109 = 218

Therefore, the value for common factors is 218.

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 = 80242373040/(1x218)

LCM = 80242373040/218

LCM = 368084280

Thus, we can understand that the LCM of 545,642,263,872 is 368084280.
