Given numbers are 646,883,129,556,857

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

The LCM of 646,883,129,556,857 is 17531075080812.

Find LCM of 646,883,129,556,857 with Prime Factorization

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

2 x 323 x 883 x 129 x 278 x 857 = 17531075080812

Therefore, the lowest common multiple of 646,883,129,556,857 is 17531075080812.

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.

646 x 883 x 129 x 556 x 857 = 35062150161624

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

883 : 1, 883

129 : 1, 3, 43, 129

556 : 1, 2, 4, 139, 278, 556

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,883,129,556,857, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

883:883

129:3x 43

556:2x 2x 139

857:857

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 35062150161624/(1x2)

LCM = 35062150161624/2

LCM = 17531075080812

Thus, we can understand that the LCM of 646,883,129,556,857 is 17531075080812.
