The LCM of 117,468,621,231 is 2486484.

Find LCM of 117,468,621,231 with Prime Factorization


3 117, 468, 621, 231
3 39, 156, 207, 77
13 13, 52, 69, 77
1, 4, 69, 77

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

3 x 3 x 13 x 1 x 4 x 69 x 77 = 2486484

Therefore, the lowest common multiple of 117,468,621,231 is 2486484.

LCM Formula to Find Lowest Common Multiple of 117,468,621,231

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.

117 x 468 x 621 x 231 = 7854802956

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.

117 : 1, 3, 9, 13, 39, 117

468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468

621 : 1, 3, 9, 23, 27, 69, 207, 621

231 : 1, 3, 7, 11, 21, 33, 77, 231

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,468,621,231, is 3.

Now, the common factors can be found like this.

117:3x 3x 13

468:2x 2x 3x 3x 13

621:3x 3x 3x 23

231:3x 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.

3x 3x 3x 3x 13 = 1053

Therefore, the value for common factors is 1053.

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 = 7854802956/(3x1053)

LCM = 7854802956/3159

LCM = 2486484

Thus, we can understand that the LCM of 117,468,621,231 is 2486484.
