Given numbers are 578,180,638

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

The LCM of 578,180,638 is 16594380.

Find LCM of 578,180,638 with Prime Factorization

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

2 x 289 x 90 x 319 = 16594380

Therefore, the lowest common multiple of 578,180,638 is 16594380.

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.

578 x 180 x 638 = 66377520

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.

578 : 1, 2, 17, 34, 289, 578

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,180,638, is 2.

Now, the common factors can be found like this.

578:2x 17x 17

180:2x 2x 3x 3x 5

638:2x 11x 29

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

2 = 2

Therefore, the value for common factors is 2.

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 = 66377520/(2x2)

LCM = 66377520/4

LCM = 16594380

Thus, we can understand that the LCM of 578,180,638 is 16594380.
