Given numbers are 289,109,728,488

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

The LCM of 289,109,728,488 is 1398896408.

Find LCM of 289,109,728,488 with Prime Factorization

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

2 x 2 x 2 x 289 x 109 x 91 x 61 = 1398896408

Therefore, the lowest common multiple of 289,109,728,488 is 1398896408.

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.

289 x 109 x 728 x 488 = 11191171264

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.

289 : 1, 17, 289

109 : 1, 109

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,109,728,488, is 1.

Now, the common factors can be found like this.

289:17x 17

109:109

728:2x 2x 2x 7x 13

488:2x 2x 2x 61

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 2 = 8

Therefore, the value for common factors is 8.

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 = 11191171264/(1x8)

LCM = 11191171264/8

LCM = 1398896408

Thus, we can understand that the LCM of 289,109,728,488 is 1398896408.
