Calculate the LCM of 789,172,342,270

Given numbers are 789,172,342,270

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

The LCM of 789,172,342,270 is 116030340.

Find LCM of 789,172,342,270 with Prime Factorization


2 789, 172, 342, 270
3 789, 86, 171, 135
3 263, 86, 57, 45
263, 86, 19, 15

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

2 x 3 x 3 x 263 x 86 x 19 x 15 = 116030340

Therefore, the lowest common multiple of 789,172,342,270 is 116030340.

LCM Formula to Find Lowest Common Multiple of 789,172,342,270

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.

789 x 172 x 342 x 270 = 12531276720

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.

789 : 1, 3, 263, 789

172 : 1, 2, 4, 43, 86, 172

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,172,342,270, is 1.

Now, the common factors can be found like this.

789:3x 263

172:2x 2x 43

342:2x 3x 3x 19

270:2x 3x 3x 3x 5

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 3x 3 = 108

Therefore, the value for common factors is 108.

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 = 12531276720/(1x108)

LCM = 12531276720/108

LCM = 116030340

Thus, we can understand that the LCM of 789,172,342,270 is 116030340.
