Calculate the LCM of 872,138,848,115

Given numbers are 872,138,848,115

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

The LCM of 872,138,848,115 is 31889040.

Find LCM of 872,138,848,115 with Prime Factorization


2 872, 138, 848, 115
2 436, 69, 424, 115
2 218, 69, 212, 115
23 109, 69, 106, 115
109, 3, 106, 5

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

2 x 2 x 2 x 23 x 109 x 3 x 106 x 5 = 31889040

Therefore, the lowest common multiple of 872,138,848,115 is 31889040.

LCM Formula to Find Lowest Common Multiple of 872,138,848,115

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.

872 x 138 x 848 x 115 = 11735166720

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.

872 : 1, 2, 4, 8, 109, 218, 436, 872

138 : 1, 2, 3, 6, 23, 46, 69, 138

848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848

115 : 1, 5, 23, 115

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,138,848,115, is 1.

Now, the common factors can be found like this.

872:2x 2x 2x 109

138:2x 3x 23

848:2x 2x 2x 2x 53

115:5x 23

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 23 = 368

Therefore, the value for common factors is 368.

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 = 11735166720/(1x368)

LCM = 11735166720/368

LCM = 31889040

Thus, we can understand that the LCM of 872,138,848,115 is 31889040.
