Given numbers are 121,545,676,432,261

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

The LCM of 121,545,676,432,261 is 139620864240.

Find LCM of 121,545,676,432,261 with Prime Factorization

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

2 x 2 x 3 x 3 x 121 x 545 x 169 x 12 x 29 = 139620864240

Therefore, the lowest common multiple of 121,545,676,432,261 is 139620864240.

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 545 x 676 x 432 x 261 = 5026351112640

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

545 : 1, 5, 109, 545

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

261 : 1, 3, 9, 29, 87, 261

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,545,676,432,261, is 1.

Now, the common factors can be found like this.

121:11x 11

545:5x 109

676:2x 2x 13x 13

432:2x 2x 2x 2x 3x 3x 3

261:3x 3x 29

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 3 = 36

Therefore, the value for common factors is 36.

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 = 5026351112640/(1x36)

LCM = 5026351112640/36

LCM = 139620864240

Thus, we can understand that the LCM of 121,545,676,432,261 is 139620864240.
