Given numbers are 255,389,340,801,390

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

The LCM of 255,389,340,801,390 is 1377223380.

Find LCM of 255,389,340,801,390 with Prime Factorization

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

2 x 3 x 5 x 17 x 1 x 389 x 2 x 267 x 13 = 1377223380

Therefore, the lowest common multiple of 255,389,340,801,390 is 1377223380.

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.

255 x 389 x 340 x 801 x 390 = 10535758857000

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.

255 : 1, 3, 5, 15, 17, 51, 85, 255

389 : 1, 389

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

801 : 1, 3, 9, 89, 267, 801

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 255,389,340,801,390, is 1.

Now, the common factors can be found like this.

255:3x 5x 17

389:389

340:2x 2x 5x 17

801:3x 3x 89

390:2x 3x 5x 13

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 3x 5x 5x 17 = 7650

Therefore, the value for common factors is 7650.

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 = 10535758857000/(1x7650)

LCM = 10535758857000/7650

LCM = 1377223380

Thus, we can understand that the LCM of 255,389,340,801,390 is 1377223380.
