Given numbers are 488,638,305,278

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

The LCM of 488,638,305,278 is 108192040.

Find LCM of 488,638,305,278 with Prime Factorization

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

2 x 61 x 4 x 319 x 5 x 139 = 108192040

Therefore, the lowest common multiple of 488,638,305,278 is 108192040.

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.

488 x 638 x 305 x 278 = 26398857760

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.

488 : 1, 2, 4, 8, 61, 122, 244, 488

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

305 : 1, 5, 61, 305

278 : 1, 2, 139, 278

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 488,638,305,278, is 1.

Now, the common factors can be found like this.

488:2x 2x 2x 61

638:2x 11x 29

305:5x 61

278:2x 139

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

2x 2x 61 = 244

Therefore, the value for common factors is 244.

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 = 26398857760/(1x244)

LCM = 26398857760/244

LCM = 108192040

Thus, we can understand that the LCM of 488,638,305,278 is 108192040.
