The LCM of 138,116,837,686 is 765958788.

Find LCM of 138,116,837,686 with Prime Factorization


2 138, 116, 837, 686
3 69, 58, 837, 343
23, 58, 279, 343

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

2 x 3 x 23 x 58 x 279 x 343 = 765958788

Therefore, the lowest common multiple of 138,116,837,686 is 765958788.

LCM Formula to Find Lowest Common Multiple of 138,116,837,686

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 116 x 837 x 686 = 9191505456

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

116 : 1, 2, 4, 29, 58, 116

837 : 1, 3, 9, 27, 31, 93, 279, 837

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,116,837,686, is 1.

Now, the common factors can be found like this.

138:2x 3x 23

116:2x 2x 29

837:3x 3x 3x 31

686:2x 7x 7x 7

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 3 = 12

Therefore, the value for common factors is 12.

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 = 9191505456/(1x12)

LCM = 9191505456/12

LCM = 765958788

Thus, we can understand that the LCM of 138,116,837,686 is 765958788.
