Given numbers are 121,827,440,686,984

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

The LCM of 121,827,440,686,984 is 168869066520.

Find LCM of 121,827,440,686,984 with Prime Factorization

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

2 x 2 x 2 x 11 x 11 x 827 x 5 x 343 x 123 = 168869066520

Therefore, the lowest common multiple of 121,827,440,686,984 is 168869066520.

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 827 x 440 x 686 x 984 = 29720955707520

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

827 : 1, 827

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

686 : 1, 2, 7, 14, 49, 98, 343, 686

984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 121,827,440,686,984, is 1.

Now, the common factors can be found like this.

121:11x 11

827:827

440:2x 2x 2x 5x 11

686:2x 7x 7x 7

984:2x 2x 2x 3x 41

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 2x 11 = 176

Therefore, the value for common factors is 176.

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 = 29720955707520/(1x176)

LCM = 29720955707520/176

LCM = 168869066520

Thus, we can understand that the LCM of 121,827,440,686,984 is 168869066520.
