Given numbers are 518,813,121,343

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

The LCM of 518,813,121,343 is 2496903486.

Find LCM of 518,813,121,343 with Prime Factorization

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

7 x 74 x 813 x 121 x 49 = 2496903486

Therefore, the lowest common multiple of 518,813,121,343 is 2496903486.

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.

518 x 813 x 121 x 343 = 17478324402

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.

518 : 1, 2, 7, 14, 37, 74, 259, 518

813 : 1, 3, 271, 813

121 : 1, 11, 121

343 : 1, 7, 49, 343

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,813,121,343, is 1.

Now, the common factors can be found like this.

518:2x 7x 37

813:3x 271

121:11x 11

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.

7 = 7

Therefore, the value for common factors is 7.

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 = 17478324402/(1x7)

LCM = 17478324402/7

LCM = 2496903486

Thus, we can understand that the LCM of 518,813,121,343 is 2496903486.
