Given numbers are 343,212,809,688

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

The LCM of 343,212,809,688 is 10118285968.

Find LCM of 343,212,809,688 with Prime Factorization

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

2 x 2 x 343 x 53 x 809 x 172 = 10118285968

Therefore, the lowest common multiple of 343,212,809,688 is 10118285968.

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.

343 x 212 x 809 x 688 = 40473143872

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.

343 : 1, 7, 49, 343

212 : 1, 2, 4, 53, 106, 212

809 : 1, 809

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,212,809,688, is 1.

Now, the common factors can be found like this.

343:7x 7x 7

212:2x 2x 53

809:809

688:2x 2x 2x 2x 43

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 40473143872/(1x4)

LCM = 40473143872/4

LCM = 10118285968

Thus, we can understand that the LCM of 343,212,809,688 is 10118285968.
