Given numbers are 730,822,621,521,947

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

The LCM of 730,822,621,521,947 is 30642396633270.

Find LCM of 730,822,621,521,947 with Prime Factorization

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

2 x 3 x 365 x 137 x 207 x 521 x 947 = 30642396633270

Therefore, the lowest common multiple of 730,822,621,521,947 is 30642396633270.

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.

730 x 822 x 621 x 521 x 947 = 183854379799620

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.

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

822 : 1, 2, 3, 6, 137, 274, 411, 822

621 : 1, 3, 9, 23, 27, 69, 207, 621

521 : 1, 521

947 : 1, 947

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,822,621,521,947, is 1.

Now, the common factors can be found like this.

730:2x 5x 73

822:2x 3x 137

621:3x 3x 3x 23

521:521

947:947

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 183854379799620/(1x6)

LCM = 183854379799620/6

LCM = 30642396633270

Thus, we can understand that the LCM of 730,822,621,521,947 is 30642396633270.
