Given numbers are 646,386,331,993

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

The LCM of 646,386,331,993 is 123805254.

Find LCM of 646,386,331,993 with Prime Factorization

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

2 x 331 x 323 x 193 x 1 x 3 = 123805254

Therefore, the lowest common multiple of 646,386,331,993 is 123805254.

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 386 x 331 x 993 = 81959078148

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

386 : 1, 2, 193, 386

331 : 1, 331

993 : 1, 3, 331, 993

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,386,331,993, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

386:2x 193

331:331

993:3x 331

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

2x 331 = 662

Therefore, the value for common factors is 662.

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 = 81959078148/(1x662)

LCM = 81959078148/662

LCM = 123805254

Thus, we can understand that the LCM of 646,386,331,993 is 123805254.
