Calculate the LCM of 391,526,738,408

Given numbers are 391,526,738,408

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

The LCM of 391,526,738,408 is 303563016.

Find LCM of 391,526,738,408 with Prime Factorization


2 391, 526, 738, 408
3 391, 263, 369, 204
17 391, 263, 123, 68
23, 263, 123, 4

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

2 x 3 x 17 x 23 x 263 x 123 x 4 = 303563016

Therefore, the lowest common multiple of 391,526,738,408 is 303563016.

LCM Formula to Find Lowest Common Multiple of 391,526,738,408

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.

391 x 526 x 738 x 408 = 61926855264

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.

391 : 1, 17, 23, 391

526 : 1, 2, 263, 526

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,526,738,408, is 1.

Now, the common factors can be found like this.

391:17x 23

526:2x 263

738:2x 3x 3x 41

408:2x 2x 2x 3x 17

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 3x 17 = 204

Therefore, the value for common factors is 204.

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 = 61926855264/(1x204)

LCM = 61926855264/204

LCM = 303563016

Thus, we can understand that the LCM of 391,526,738,408 is 303563016.
