Given numbers are 121,777,728,909

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

The LCM of 121,777,728,909 is 2962663704.

Find LCM of 121,777,728,909 with Prime Factorization

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

3 x 7 x 121 x 37 x 104 x 303 = 2962663704

Therefore, the lowest common multiple of 121,777,728,909 is 2962663704.

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 777 x 728 x 909 = 62215937784

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

777 : 1, 3, 7, 21, 37, 111, 259, 777

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

909 : 1, 3, 9, 101, 303, 909

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,777,728,909, is 1.

Now, the common factors can be found like this.

121:11x 11

777:3x 7x 37

728:2x 2x 2x 7x 13

909:3x 3x 101

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 62215937784/(1x21)

LCM = 62215937784/21

LCM = 2962663704

Thus, we can understand that the LCM of 121,777,728,909 is 2962663704.
