Given numbers are 121,143,963,728

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

The LCM of 121,143,963,728 is 84828744.

Find LCM of 121,143,963,728 with Prime Factorization

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

11 x 13 x 11 x 1 x 963 x 56 = 84828744

Therefore, the lowest common multiple of 121,143,963,728 is 84828744.

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.

121 x 143 x 963 x 728 = 12130510392

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.

121 : 1, 11, 121

143 : 1, 11, 13, 143

963 : 1, 3, 9, 107, 321, 963

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 121,143,963,728, is 1.

Now, the common factors can be found like this.

121:11x 11

143:11x 13

963:3x 3x 107

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.

11x 13 = 143

Therefore, the value for common factors is 143.

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 = 12130510392/(1x143)

LCM = 12130510392/143

LCM = 84828744

Thus, we can understand that the LCM of 121,143,963,728 is 84828744.
