| 3 | 15, 19, 811, 12, 983 |
| 5, 19, 811, 4, 983 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 5 x 19 x 811 x 4 x 983 = 43623495360
Therefore, the lowest common multiple of 720,912,811,576,983 is 43623495360.
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.
720 x 912 x 811 x 576 x 983 = 301525599928320
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.
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
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
811 : 1, 811
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
983 : 1, 983
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,912,811,576,983, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
912:2x 2x 2x 2x 3x 19
811:811
576:2x 2x 2x 2x 2x 2x 3x 3
983:983
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 2x 2x 3x 3x 3 = 6912
Therefore, the value for common factors is 6912.
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 = 301525599928320/(1x6912)
LCM = 301525599928320/6912
LCM = 43623495360
Thus, we can understand that the LCM of 720,912,811,576,983 is 43623495360.
