Given numbers are 128,743,840,211,922

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

The LCM of 128,743,840,211,922 is 971340424320.

Find LCM of 128,743,840,211,922 with Prime Factorization

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

2 x 2 x 2 x 16 x 743 x 105 x 211 x 461 = 971340424320

Therefore, the lowest common multiple of 128,743,840,211,922 is 971340424320.

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.

128 x 743 x 840 x 211 x 922 = 15541446789120

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.

128 : 1, 2, 4, 8, 16, 32, 64, 128

743 : 1, 743

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

211 : 1, 211

922 : 1, 2, 461, 922

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,743,840,211,922, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

743:743

840:2x 2x 2x 3x 5x 7

211:211

922:2x 461

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 2 = 16

Therefore, the value for common factors is 16.

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 = 15541446789120/(1x16)

LCM = 15541446789120/16

LCM = 971340424320

Thus, we can understand that the LCM of 128,743,840,211,922 is 971340424320.
