Find LCM of 809,918,575,408,454 with Prime Factorization


2 809, 918, 575, 408, 454
3 809, 459, 575, 204, 227
17 809, 153, 575, 68, 227
809, 9, 575, 4, 227

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

2 x 3 x 17 x 809 x 9 x 575 x 4 x 227 = 387743830200

Therefore, the lowest common multiple of 809,918,575,408,454 is 387743830200.

LCM Formula to Find Lowest Common Multiple of 809,918,575,408,454

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.

809 x 918 x 575 x 408 x 454 = 79099741360800

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.

809 : 1, 809

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

575 : 1, 5, 23, 25, 115, 575

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

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,918,575,408,454, is 1.

Now, the common factors can be found like this.

809:809

918:2x 3x 3x 3x 17

575:5x 5x 23

408:2x 2x 2x 3x 17

454:2x 227

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 = 79099741360800/(1x204)

LCM = 79099741360800/204

LCM = 387743830200

Thus, we can understand that the LCM of 809,918,575,408,454 is 387743830200.
