Given numbers are 121,844,545,868

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

The LCM of 121,844,545,868 is 12077694860.

Find LCM of 121,844,545,868 with Prime Factorization

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

2 x 2 x 121 x 211 x 545 x 217 = 12077694860

Therefore, the lowest common multiple of 121,844,545,868 is 12077694860.

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 844 x 545 x 868 = 48310779440

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

844 : 1, 2, 4, 211, 422, 844

545 : 1, 5, 109, 545

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,844,545,868, is 1.

Now, the common factors can be found like this.

121:11x 11

844:2x 2x 211

545:5x 109

868:2x 2x 7x 31

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 = 48310779440/(1x4)

LCM = 48310779440/4

LCM = 12077694860

Thus, we can understand that the LCM of 121,844,545,868 is 12077694860.
