Given numbers are 272,454,470,221,291

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

The LCM of 272,454,470,221,291 is 54890724720.

Find LCM of 272,454,470,221,291 with Prime Factorization

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

2 x 17 x 8 x 227 x 235 x 13 x 291 = 54890724720

Therefore, the lowest common multiple of 272,454,470,221,291 is 54890724720.

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.

272 x 454 x 470 x 221 x 291 = 3732569280960

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.

272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272

454 : 1, 2, 227, 454

470 : 1, 2, 5, 10, 47, 94, 235, 470

221 : 1, 13, 17, 221

291 : 1, 3, 97, 291

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 272,454,470,221,291, is 1.

Now, the common factors can be found like this.

272:2x 2x 2x 2x 17

454:2x 227

470:2x 5x 47

221:13x 17

291:3x 97

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 17 = 68

Therefore, the value for common factors is 68.

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 = 3732569280960/(1x68)

LCM = 3732569280960/68

LCM = 54890724720

Thus, we can understand that the LCM of 272,454,470,221,291 is 54890724720.
