Calculate the LCM of 308,858,655,311

Given numbers are 308,858,655,311

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

The LCM of 308,858,655,311 is 2446904460.

Find LCM of 308,858,655,311 with Prime Factorization


2 308, 858, 655, 311
11 154, 429, 655, 311
14, 39, 655, 311

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

2 x 11 x 14 x 39 x 655 x 311 = 2446904460

Therefore, the lowest common multiple of 308,858,655,311 is 2446904460.

LCM Formula to Find Lowest Common Multiple of 308,858,655,311

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.

308 x 858 x 655 x 311 = 53831898120

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.

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

655 : 1, 5, 131, 655

311 : 1, 311

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,858,655,311, is 1.

Now, the common factors can be found like this.

308:2x 2x 7x 11

858:2x 3x 11x 13

655:5x 131

311:311

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 53831898120/(1x22)

LCM = 53831898120/22

LCM = 2446904460

Thus, we can understand that the LCM of 308,858,655,311 is 2446904460.
