| 23 | 989, 1, 5, 157, 23 |
| 43, 1, 5, 157, 1 |
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 23 x 43 x 1 x 5 x 157 x 1 = 558982800
Therefore, the lowest common multiple of 989,720,900,157,368 is 558982800.
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.
989 x 720 x 900 x 157 x 368 = 37027020672000
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.
989 : 1, 23, 43, 989
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
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
157 : 1, 157
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,720,900,157,368, is 1.
Now, the common factors can be found like this.
989:23x 43
720:2x 2x 2x 2x 3x 3x 5
900:2x 2x 3x 3x 5x 5
157:157
368:2x 2x 2x 2x 23
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 5x 23 = 66240
Therefore, the value for common factors is 66240.
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 = 37027020672000/(1x66240)
LCM = 37027020672000/66240
LCM = 558982800
Thus, we can understand that the LCM of 989,720,900,157,368 is 558982800.
