Given numbers are 680,990,730,803

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

The LCM of 680,990,730,803 is 4914360.

Find LCM of 680,990,730,803 with Prime Factorization

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

2 x 5 x 11 x 73 x 68 x 9 x 1 x 1 = 4914360

Therefore, the lowest common multiple of 680,990,730,803 is 4914360.

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.

680 x 990 x 730 x 803 = 394623108000

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.

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

730 : 1, 2, 5, 10, 73, 146, 365, 730

803 : 1, 11, 73, 803

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,990,730,803, is 1.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

990:2x 3x 3x 5x 11

730:2x 5x 73

803:11x 73

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

2x 2x 5x 5x 11x 73 = 80300

Therefore, the value for common factors is 80300.

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 = 394623108000/(1x80300)

LCM = 394623108000/80300

LCM = 4914360

Thus, we can understand that the LCM of 680,990,730,803 is 4914360.
