Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 997 x 443 x 19 x 11 x 2 = 66462652080
Therefore, the lowest common multiple of 997,443,760,198,720 is 66462652080.
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.
997 x 443 x 760 x 198 x 720 = 47853109497600
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.
997 : 1, 997
443 : 1, 443
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
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 997,443,760,198,720, is 1.
Now, the common factors can be found like this.
997:997
443:443
760:2x 2x 2x 5x 19
198:2x 3x 3x 11
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 2x 2x 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 47853109497600/(1x720)
LCM = 47853109497600/720
LCM = 66462652080
Thus, we can understand that the LCM of 997,443,760,198,720 is 66462652080.
