Given numbers are 646,629,323,71

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

The LCM of 646,629,323,71 is 1697042.

Find LCM of 646,629,323,71 with Prime Factorization

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

17 x 19 x 2 x 37 x 1 x 71 = 1697042

Therefore, the lowest common multiple of 646,629,323,71 is 1697042.

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.

646 x 629 x 323 x 71 = 9318457622

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

629 : 1, 17, 37, 629

323 : 1, 17, 19, 323

71 : 1, 71

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,629,323,71, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

629:17x 37

323:17x 19

71:71

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

17x 17x 19 = 5491

Therefore, the value for common factors is 5491.

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 = 9318457622/(1x5491)

LCM = 9318457622/5491

LCM = 1697042

Thus, we can understand that the LCM of 646,629,323,71 is 1697042.
