Given numbers are 121,260,754,489,140

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

The LCM of 121,260,754,489,140 is 3122939820.

Find LCM of 121,260,754,489,140 with Prime Factorization

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

2 x 2 x 5 x 13 x 121 x 1 x 29 x 489 x 7 = 3122939820

Therefore, the lowest common multiple of 121,260,754,489,140 is 3122939820.

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 260 x 754 x 489 x 140 = 1623928706400

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

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

754 : 1, 2, 13, 26, 29, 58, 377, 754

489 : 1, 3, 163, 489

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,260,754,489,140, is 1.

Now, the common factors can be found like this.

121:11x 11

260:2x 2x 5x 13

754:2x 13x 29

489:3x 163

140:2x 2x 5x 7

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 2x 5x 13 = 520

Therefore, the value for common factors is 520.

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 = 1623928706400/(1x520)

LCM = 1623928706400/520

LCM = 3122939820

Thus, we can understand that the LCM of 121,260,754,489,140 is 3122939820.
