Calculate the LCM of 342,783,378,789

Given numbers are 342,783,378,789

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

The LCM of 342,783,378,789 is 54777114.

Find LCM of 342,783,378,789 with Prime Factorization


2 342, 783, 378, 789
3 171, 783, 189, 789
3 57, 261, 63, 263
3 19, 87, 21, 263
19, 29, 7, 263

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

2 x 3 x 3 x 3 x 19 x 29 x 7 x 263 = 54777114

Therefore, the lowest common multiple of 342,783,378,789 is 54777114.

LCM Formula to Find Lowest Common Multiple of 342,783,378,789

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.

342 x 783 x 378 x 789 = 79865032212

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.

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

783 : 1, 3, 9, 27, 29, 87, 261, 783

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

789 : 1, 3, 263, 789

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,783,378,789, is 3.

Now, the common factors can be found like this.

342:2x 3x 3x 19

783:3x 3x 3x 29

378:2x 3x 3x 3x 7

789:3x 263

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 3x 3x 3x 3 = 486

Therefore, the value for common factors is 486.

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 = 79865032212/(3x486)

LCM = 79865032212/1458

LCM = 54777114

Thus, we can understand that the LCM of 342,783,378,789 is 54777114.
