Calculate the LCM of 391,677,731,400

Given numbers are 391,677,731,400

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

The LCM of 391,677,731,400 is 4552960400.

Find LCM of 391,677,731,400 with Prime Factorization


17 391, 677, 731, 400
23, 677, 43, 400

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

17 x 23 x 677 x 43 x 400 = 4552960400

Therefore, the lowest common multiple of 391,677,731,400 is 4552960400.

LCM Formula to Find Lowest Common Multiple of 391,677,731,400

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 677 x 731 x 400 = 77400326800

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

677 : 1, 677

731 : 1, 17, 43, 731

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,677,731,400, is 1.

Now, the common factors can be found like this.

391:17x 23

677:677

731:17x 43

400:2x 2x 2x 2x 5x 5

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

17 = 17

Therefore, the value for common factors is 17.

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 = 77400326800/(1x17)

LCM = 77400326800/17

LCM = 4552960400

Thus, we can understand that the LCM of 391,677,731,400 is 4552960400.
