Given numbers are 660,425,773,720,687

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

The LCM of 660,425,773,720,687 is 119167844400.

Find LCM of 660,425,773,720,687 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 85 x 773 x 12 x 229 = 119167844400

Therefore, the lowest common multiple of 660,425,773,720,687 is 119167844400.

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.

660 x 425 x 773 x 720 x 687 = 107251059960000

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

425 : 1, 5, 17, 25, 85, 425

773 : 1, 773

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

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,425,773,720,687, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

425:5x 5x 17

773:773

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

687:3x 229

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 3x 3x 5x 5 = 900

Therefore, the value for common factors is 900.

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 = 107251059960000/(1x900)

LCM = 107251059960000/900

LCM = 119167844400

Thus, we can understand that the LCM of 660,425,773,720,687 is 119167844400.
