Given numbers are 489,427,278,180

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

The LCM of 489,427,278,180 is 1741417020.

Find LCM of 489,427,278,180 with Prime Factorization

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

2 x 3 x 163 x 427 x 139 x 30 = 1741417020

Therefore, the lowest common multiple of 489,427,278,180 is 1741417020.

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 427 x 278 x 180 = 10448502120

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

427 : 1, 7, 61, 427

278 : 1, 2, 139, 278

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,427,278,180, is 1.

Now, the common factors can be found like this.

489:3x 163

427:7x 61

278:2x 139

180:2x 2x 3x 3x 5

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 10448502120/(1x6)

LCM = 10448502120/6

LCM = 1741417020

Thus, we can understand that the LCM of 489,427,278,180 is 1741417020.
