Given numbers are 720,912,788,921,439

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

The LCM of 720,912,788,921,439 is 363207844080.

Find LCM of 720,912,788,921,439 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 15 x 19 x 197 x 307 x 439 = 363207844080

Therefore, the lowest common multiple of 720,912,788,921,439 is 363207844080.

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 912 x 788 x 921 x 439 = 209207718190080

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

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

788 : 1, 2, 4, 197, 394, 788

921 : 1, 3, 307, 921

439 : 1, 439

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,912,788,921,439, is 1.

Now, the common factors can be found like this.

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

912:2x 2x 2x 2x 3x 19

788:2x 2x 197

921:3x 307

439:439

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 2x 2x 2x 2x 3x 3 = 576

Therefore, the value for common factors is 576.

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 = 209207718190080/(1x576)

LCM = 209207718190080/576

LCM = 363207844080

Thus, we can understand that the LCM of 720,912,788,921,439 is 363207844080.
