Given numbers are 556,788,121,921

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

The LCM of 556,788,121,921 is 12206355612.

Find LCM of 556,788,121,921 with Prime Factorization

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

2 x 2 x 139 x 197 x 121 x 921 = 12206355612

Therefore, the lowest common multiple of 556,788,121,921 is 12206355612.

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.

556 x 788 x 121 x 921 = 48825422448

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.

556 : 1, 2, 4, 139, 278, 556

788 : 1, 2, 4, 197, 394, 788

121 : 1, 11, 121

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,788,121,921, is 1.

Now, the common factors can be found like this.

556:2x 2x 139

788:2x 2x 197

121:11x 11

921:3x 307

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 48825422448/(1x4)

LCM = 48825422448/4

LCM = 12206355612

Thus, we can understand that the LCM of 556,788,121,921 is 12206355612.
