Given numbers are 720,617,993,331,663

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

The LCM of 720,617,993,331,663 is 32496600240.

Find LCM of 720,617,993,331,663 with Prime Factorization

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

3 x 331 x 240 x 617 x 1 x 1 x 221 = 32496600240

Therefore, the lowest common multiple of 720,617,993,331,663 is 32496600240.

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.

720 x 617 x 993 x 331 x 663 = 96807372114960

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.

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

617 : 1, 617

993 : 1, 3, 331, 993

331 : 1, 331

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,617,993,331,663, is 1.

Now, the common factors can be found like this.

720:2x 2x 2x 2x 3x 3x 5

617:617

993:3x 331

331:331

663:3x 13x 17

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

3x 3x 331 = 2979

Therefore, the value for common factors is 2979.

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 = 96807372114960/(1x2979)

LCM = 96807372114960/2979

LCM = 32496600240

Thus, we can understand that the LCM of 720,617,993,331,663 is 32496600240.
