The LCM of 454,499,686,343 is 77705278.

Find LCM of 454,499,686,343 with Prime Factorization


2 454, 499, 686, 343
7 227, 499, 343, 343
7 227, 499, 49, 49
7 227, 499, 7, 7
227, 499, 1, 1

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

2 x 7 x 7 x 7 x 227 x 499 x 1 x 1 = 77705278

Therefore, the lowest common multiple of 454,499,686,343 is 77705278.

LCM Formula to Find Lowest Common Multiple of 454,499,686,343

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.

454 x 499 x 686 x 343 = 53305820708

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.

454 : 1, 2, 227, 454

499 : 1, 499

686 : 1, 2, 7, 14, 49, 98, 343, 686

343 : 1, 7, 49, 343

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,499,686,343, is 1.

Now, the common factors can be found like this.

454:2x 227

499:499

686:2x 7x 7x 7

343:7x 7x 7

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

2x 7x 7x 7 = 686

Therefore, the value for common factors is 686.

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 = 53305820708/(1x686)

LCM = 53305820708/686

LCM = 77705278

Thus, we can understand that the LCM of 454,499,686,343 is 77705278.
