Calculate the LCM of 904,390,811,512

Given numbers are 904,390,811,512

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

The LCM of 904,390,811,512 is 9149637120.

Find LCM of 904,390,811,512 with Prime Factorization


2 904, 390, 811, 512
2 452, 195, 811, 256
2 226, 195, 811, 128
113, 195, 811, 64

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

2 x 2 x 2 x 113 x 195 x 811 x 64 = 9149637120

Therefore, the lowest common multiple of 904,390,811,512 is 9149637120.

LCM Formula to Find Lowest Common Multiple of 904,390,811,512

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.

904 x 390 x 811 x 512 = 146394193920

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.

904 : 1, 2, 4, 8, 113, 226, 452, 904

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

811 : 1, 811

512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,390,811,512, is 1.

Now, the common factors can be found like this.

904:2x 2x 2x 113

390:2x 3x 5x 13

811:811

512:2x 2x 2x 2x 2x 2x 2x 2x 2

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 146394193920/(1x16)

LCM = 146394193920/16

LCM = 9149637120

Thus, we can understand that the LCM of 904,390,811,512 is 9149637120.
