Given numbers are 121,781,370,882

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

The LCM of 121,781,370,882 is 1401793470.

Find LCM of 121,781,370,882 with Prime Factorization

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

2 x 11 x 11 x 71 x 185 x 441 = 1401793470

Therefore, the lowest common multiple of 121,781,370,882 is 1401793470.

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 781 x 370 x 882 = 30839456340

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

781 : 1, 11, 71, 781

370 : 1, 2, 5, 10, 37, 74, 185, 370

882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,781,370,882, is 1.

Now, the common factors can be found like this.

121:11x 11

781:11x 71

370:2x 5x 37

882:2x 3x 3x 7x 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 11 = 22

Therefore, the value for common factors is 22.

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 = 30839456340/(1x22)

LCM = 30839456340/22

LCM = 1401793470

Thus, we can understand that the LCM of 121,781,370,882 is 1401793470.
