Given numbers are 663,643,921,511,857

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

The LCM of 663,643,921,511,857 is 57314511983001.

Find LCM of 663,643,921,511,857 with Prime Factorization

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

3 x 221 x 643 x 307 x 511 x 857 = 57314511983001

Therefore, the lowest common multiple of 663,643,921,511,857 is 57314511983001.

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.

663 x 643 x 921 x 511 x 857 = 171943535949003

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.

663 : 1, 3, 13, 17, 39, 51, 221, 663

643 : 1, 643

921 : 1, 3, 307, 921

511 : 1, 7, 73, 511

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,643,921,511,857, is 1.

Now, the common factors can be found like this.

663:3x 13x 17

643:643

921:3x 307

511:7x 73

857:857

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

3 = 3

Therefore, the value for common factors is 3.

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 = 171943535949003/(1x3)

LCM = 171943535949003/3

LCM = 57314511983001

Thus, we can understand that the LCM of 663,643,921,511,857 is 57314511983001.
