Given numbers are 121,930,872,654,243

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

The LCM of 121,930,872,654,243 is 3974109480.

Find LCM of 121,930,872,654,243 with Prime Factorization

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

2 x 3 x 109 x 121 x 155 x 4 x 1 x 81 = 3974109480

Therefore, the lowest common multiple of 121,930,872,654,243 is 3974109480.

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 930 x 872 x 654 x 243 = 15594405599520

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

930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930

872 : 1, 2, 4, 8, 109, 218, 436, 872

654 : 1, 2, 3, 6, 109, 218, 327, 654

243 : 1, 3, 9, 27, 81, 243

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,930,872,654,243, is 1.

Now, the common factors can be found like this.

121:11x 11

930:2x 3x 5x 31

872:2x 2x 2x 109

654:2x 3x 109

243:3x 3x 3x 3x 3

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

2x 2x 3x 3x 109 = 3924

Therefore, the value for common factors is 3924.

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 = 15594405599520/(1x3924)

LCM = 15594405599520/3924

LCM = 3974109480

Thus, we can understand that the LCM of 121,930,872,654,243 is 3974109480.
