Given numbers are 489,126,879,831

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

The LCM of 489,126,879,831 is 1666884618.

Find LCM of 489,126,879,831 with Prime Factorization

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

3 x 163 x 42 x 293 x 277 = 1666884618

Therefore, the lowest common multiple of 489,126,879,831 is 1666884618.

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.

489 x 126 x 879 x 831 = 45005884686

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.

489 : 1, 3, 163, 489

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

879 : 1, 3, 293, 879

831 : 1, 3, 277, 831

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,126,879,831, is 3.

Now, the common factors can be found like this.

489:3x 163

126:2x 3x 3x 7

879:3x 293

831:3x 277

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 45005884686/(3x9)

LCM = 45005884686/27

LCM = 1666884618

Thus, we can understand that the LCM of 489,126,879,831 is 1666884618.
