| 5 | 101, 83, 80, 103, 5 |
| 101, 83, 16, 103, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 101 x 83 x 16 x 103 x 1 = 4973466240
Therefore, the lowest common multiple of 909,747,640,824,360 is 4973466240.
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.
909 x 747 x 640 x 824 x 360 = 128912244940800
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.
909 : 1, 3, 9, 101, 303, 909
747 : 1, 3, 9, 83, 249, 747
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
824 : 1, 2, 4, 8, 103, 206, 412, 824
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,747,640,824,360, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
747:3x 3x 83
640:2x 2x 2x 2x 2x 2x 2x 5
824:2x 2x 2x 103
360:2x 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 2x 2x 3x 3x 3x 3x 5 = 25920
Therefore, the value for common factors is 25920.
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 = 128912244940800/(1x25920)
LCM = 128912244940800/25920
LCM = 4973466240
Thus, we can understand that the LCM of 909,747,640,824,360 is 4973466240.
