Given numbers are 121,381,680,605,444

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

The LCM of 121,381,680,605,444 is 1159901160.

Find LCM of 121,381,680,605,444 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 11 x 1 x 127 x 34 x 1 x 37 = 1159901160

Therefore, the lowest common multiple of 121,381,680,605,444 is 1159901160.

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 381 x 680 x 605 x 444 = 8420882421600

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

381 : 1, 3, 127, 381

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

605 : 1, 5, 11, 55, 121, 605

444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,381,680,605,444, is 1.

Now, the common factors can be found like this.

121:11x 11

381:3x 127

680:2x 2x 2x 5x 17

605:5x 11x 11

444:2x 2x 3x 37

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 5x 11x 11 = 7260

Therefore, the value for common factors is 7260.

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 = 8420882421600/(1x7260)

LCM = 8420882421600/7260

LCM = 1159901160

Thus, we can understand that the LCM of 121,381,680,605,444 is 1159901160.
