Find LCM of 240,740,437,720,280 with Prime Factorization
| 2 | 240, 740, 437, 720, 280 |
| 2 | 120, 370, 437, 360, 140 |
| 2 | 60, 185, 437, 180, 70 |
| 2 | 30, 185, 437, 90, 35 |
| 3 | 15, 185, 437, 45, 35 |
| 5 | 5, 185, 437, 15, 35 |
| 1, 37, 437, 3, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 1 x 37 x 437 x 3 x 7 = 81491760
Therefore, the lowest common multiple of 240,740,437,720,280 is 81491760.
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.
240 x 740 x 437 x 720 x 280 = 15646417920000
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.
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
437 : 1, 19, 23, 437
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
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,740,437,720,280, is 1.
Now, the common factors can be found like this.
240:2x 2x 2x 2x 3x 5
740:2x 2x 5x 37
437:19x 23
720:2x 2x 2x 2x 3x 3x 5
280:2x 2x 2x 5x 7
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 2x 3x 5x 5x 5 = 192000
Therefore, the value for common factors is 192000.
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 = 15646417920000/(1x192000)
LCM = 15646417920000/192000
LCM = 81491760
Thus, we can understand that the LCM of 240,740,437,720,280 is 81491760.
