Given numbers are 715,305,560,730,446

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

The LCM of 715,305,560,730,446 is 79520961520.

Find LCM of 715,305,560,730,446 with Prime Factorization

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

2 x 5 x 143 x 61 x 56 x 73 x 223 = 79520961520

Therefore, the lowest common multiple of 715,305,560,730,446 is 79520961520.

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.

715 x 305 x 560 x 730 x 446 = 39760480760000

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.

715 : 1, 5, 11, 13, 55, 65, 143, 715

305 : 1, 5, 61, 305

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

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

446 : 1, 2, 223, 446

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,305,560,730,446, is 1.

Now, the common factors can be found like this.

715:5x 11x 13

305:5x 61

560:2x 2x 2x 2x 5x 7

730:2x 5x 73

446:2x 223

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 5 = 500

Therefore, the value for common factors is 500.

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 = 39760480760000/(1x500)

LCM = 39760480760000/500

LCM = 79520961520

Thus, we can understand that the LCM of 715,305,560,730,446 is 79520961520.
