Given numbers are 489,254,669,438

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

The LCM of 489,254,669,438 is 2021949474.

Find LCM of 489,254,669,438 with Prime Factorization

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

2 x 3 x 163 x 127 x 223 x 73 = 2021949474

Therefore, the lowest common multiple of 489,254,669,438 is 2021949474.

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 254 x 669 x 438 = 36395090532

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

254 : 1, 2, 127, 254

669 : 1, 3, 223, 669

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,254,669,438, is 1.

Now, the common factors can be found like this.

489:3x 163

254:2x 127

669:3x 223

438:2x 3x 73

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 = 36395090532/(1x18)

LCM = 36395090532/18

LCM = 2021949474

Thus, we can understand that the LCM of 489,254,669,438 is 2021949474.
