Calculate the LCM of 138,930,902,308

Given numbers are 138,930,902,308

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

The LCM of 138,930,902,308 is 135056460.

Find LCM of 138,930,902,308 with Prime Factorization


2 138, 930, 902, 308
3 69, 465, 451, 154
11 23, 155, 451, 154
23, 155, 41, 14

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

2 x 3 x 11 x 23 x 155 x 41 x 14 = 135056460

Therefore, the lowest common multiple of 138,930,902,308 is 135056460.

LCM Formula to Find Lowest Common Multiple of 138,930,902,308

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.

138 x 930 x 902 x 308 = 35654905440

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.

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

930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930

902 : 1, 2, 11, 22, 41, 82, 451, 902

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,930,902,308, is 2.

Now, the common factors can be found like this.

138:2x 3x 23

930:2x 3x 5x 31

902:2x 11x 41

308:2x 2x 7x 11

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 3x 11 = 132

Therefore, the value for common factors is 132.

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 = 35654905440/(2x132)

LCM = 35654905440/264

LCM = 135056460

Thus, we can understand that the LCM of 138,930,902,308 is 135056460.
