Given numbers are 279,879,642,172

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

The LCM of 279,879,642,172 is 1504471788.

Find LCM of 279,879,642,172 with Prime Factorization

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

2 x 3 x 93 x 293 x 107 x 86 = 1504471788

Therefore, the lowest common multiple of 279,879,642,172 is 1504471788.

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.

279 x 879 x 642 x 172 = 27080492184

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.

279 : 1, 3, 9, 31, 93, 279

879 : 1, 3, 293, 879

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

172 : 1, 2, 4, 43, 86, 172

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,879,642,172, is 1.

Now, the common factors can be found like this.

279:3x 3x 31

879:3x 293

642:2x 3x 107

172:2x 2x 43

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 27080492184/(1x18)

LCM = 27080492184/18

LCM = 1504471788

Thus, we can understand that the LCM of 279,879,642,172 is 1504471788.
