Calculate the LCM of 491,347,150,405

Given numbers are 491,347,150,405

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

The LCM of 491,347,150,405 is 690026850.

Find LCM of 491,347,150,405 with Prime Factorization


3 491, 347, 150, 405
5 491, 347, 50, 135
491, 347, 10, 27

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

3 x 5 x 491 x 347 x 10 x 27 = 690026850

Therefore, the lowest common multiple of 491,347,150,405 is 690026850.

LCM Formula to Find Lowest Common Multiple of 491,347,150,405

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.

491 x 347 x 150 x 405 = 10350402750

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.

491 : 1, 491

347 : 1, 347

150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,347,150,405, is 1.

Now, the common factors can be found like this.

491:491

347:347

150:2x 3x 5x 5

405:3x 3x 3x 3x 5

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 10350402750/(1x15)

LCM = 10350402750/15

LCM = 690026850

Thus, we can understand that the LCM of 491,347,150,405 is 690026850.
