Calculate the LCM of 128,803,440,828

Given numbers are 128,803,440,828

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

The LCM of 128,803,440,828 is 106381440.

Find LCM of 128,803,440,828 with Prime Factorization


2 128, 803, 440, 828
2 64, 803, 220, 414
2 32, 803, 110, 207
11 16, 803, 55, 207
16, 73, 5, 207

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

2 x 2 x 2 x 11 x 16 x 73 x 5 x 207 = 106381440

Therefore, the lowest common multiple of 128,803,440,828 is 106381440.

LCM Formula to Find Lowest Common Multiple of 128,803,440,828

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.

128 x 803 x 440 x 828 = 37446266880

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.

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

803 : 1, 11, 73, 803

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,803,440,828, is 1.

Now, the common factors can be found like this.

128:2x 2x 2x 2x 2x 2x 2

803:11x 73

440:2x 2x 2x 5x 11

828:2x 2x 3x 3x 23

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 2x 2x 11 = 352

Therefore, the value for common factors is 352.

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 = 37446266880/(1x352)

LCM = 37446266880/352

LCM = 106381440

Thus, we can understand that the LCM of 128,803,440,828 is 106381440.
