Given numbers are 305,317,206,720

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

The LCM of 305,317,206,720 is 1434031920.

Find LCM of 305,317,206,720 with Prime Factorization

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

2 x 5 x 61 x 317 x 103 x 72 = 1434031920

Therefore, the lowest common multiple of 305,317,206,720 is 1434031920.

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.

305 x 317 x 206 x 720 = 14340319200

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.

305 : 1, 5, 61, 305

317 : 1, 317

206 : 1, 2, 103, 206

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,317,206,720, is 1.

Now, the common factors can be found like this.

305:5x 61

317:317

206:2x 103

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

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 14340319200/(1x10)

LCM = 14340319200/10

LCM = 1434031920

Thus, we can understand that the LCM of 305,317,206,720 is 1434031920.
