The LCM of 378,551,976,865 is 87918309360.

Find LCM of 378,551,976,865 with Prime Factorization


2 378, 551, 976, 865
189, 551, 488, 865

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

2 x 189 x 551 x 488 x 865 = 87918309360

Therefore, the lowest common multiple of 378,551,976,865 is 87918309360.

LCM Formula to Find Lowest Common Multiple of 378,551,976,865

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.

378 x 551 x 976 x 865 = 175836618720

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.

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

551 : 1, 19, 29, 551

976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,551,976,865, is 1.

Now, the common factors can be found like this.

378:2x 3x 3x 3x 7

551:19x 29

976:2x 2x 2x 2x 61

865:5x 173

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

2 = 2

Therefore, the value for common factors is 2.

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 = 175836618720/(1x2)

LCM = 175836618720/2

LCM = 87918309360

Thus, we can understand that the LCM of 378,551,976,865 is 87918309360.
