Given numbers are 443,818,821,760,990

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

The LCM of 443,818,821,760,990 is 11192290611480.

Find LCM of 443,818,821,760,990 with Prime Factorization

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

2 x 5 x 443 x 409 x 821 x 76 x 99 = 11192290611480

Therefore, the lowest common multiple of 443,818,821,760,990 is 11192290611480.

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.

443 x 818 x 821 x 760 x 990 = 223845812229600

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.

443 : 1, 443

818 : 1, 2, 409, 818

821 : 1, 821

760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 443,818,821,760,990, is 1.

Now, the common factors can be found like this.

443:443

818:2x 409

821:821

760:2x 2x 2x 5x 19

990:2x 3x 3x 5x 11

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 5 = 20

Therefore, the value for common factors is 20.

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 = 223845812229600/(1x20)

LCM = 223845812229600/20

LCM = 11192290611480

Thus, we can understand that the LCM of 443,818,821,760,990 is 11192290611480.
