Given numbers are 663,841,728

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

The LCM of 663,841,728 is 31224648.

Find LCM of 663,841,728 with Prime Factorization

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

13 x 51 x 841 x 56 = 31224648

Therefore, the lowest common multiple of 663,841,728 is 31224648.

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.

663 x 841 x 728 = 405920424

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.

663 : 1, 3, 13, 17, 39, 51, 221, 663

841 : 1, 29, 841

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,841,728, is 1.

Now, the common factors can be found like this.

663:3x 13x 17

841:29x 29

728:2x 2x 2x 7x 13

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

13 = 13

Therefore, the value for common factors is 13.

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 = 405920424/(1x13)

LCM = 405920424/13

LCM = 31224648

Thus, we can understand that the LCM of 663,841,728 is 31224648.
