Calculate the LCM of 558,421,857,122

Given numbers are 558,421,857,122

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

The LCM of 558,421,857,122 is 12280808286.

Find LCM of 558,421,857,122 with Prime Factorization


2 558, 421, 857, 122
279, 421, 857, 61

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

2 x 279 x 421 x 857 x 61 = 12280808286

Therefore, the lowest common multiple of 558,421,857,122 is 12280808286.

LCM Formula to Find Lowest Common Multiple of 558,421,857,122

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.

558 x 421 x 857 x 122 = 24561616572

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.

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

421 : 1, 421

857 : 1, 857

122 : 1, 2, 61, 122

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,421,857,122, is 1.

Now, the common factors can be found like this.

558:2x 3x 3x 31

421:421

857:857

122:2x 61

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 = 24561616572/(1x2)

LCM = 24561616572/2

LCM = 12280808286

Thus, we can understand that the LCM of 558,421,857,122 is 12280808286.
