Given numbers are 245,409,272,864

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

The LCM of 245,409,272,864 is 1471811040.

Find LCM of 245,409,272,864 with Prime Factorization

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

2 x 2 x 2 x 2 x 245 x 409 x 17 x 54 = 1471811040

Therefore, the lowest common multiple of 245,409,272,864 is 1471811040.

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.

245 x 409 x 272 x 864 = 23548976640

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.

245 : 1, 5, 7, 35, 49, 245

409 : 1, 409

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

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 245,409,272,864, is 1.

Now, the common factors can be found like this.

245:5x 7x 7

409:409

272:2x 2x 2x 2x 17

864:2x 2x 2x 2x 2x 3x 3x 3

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 23548976640/(1x16)

LCM = 23548976640/16

LCM = 1471811040

Thus, we can understand that the LCM of 245,409,272,864 is 1471811040.
