Find LCM of 960,445,740,614,640 with Prime Factorization
| 2 | 960, 445, 740, 614, 640 |
| 2 | 480, 445, 370, 307, 320 |
| 2 | 240, 445, 185, 307, 160 |
| 2 | 120, 445, 185, 307, 80 |
| 2 | 60, 445, 185, 307, 40 |

| 5 | 15, 445, 185, 307, 10 |
| 3, 89, 37, 307, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 5 x 3 x 89 x 37 x 307 x 2 = 1941025920
Therefore, the lowest common multiple of 960,445,740,614,640 is 1941025920.
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.
960 x 445 x 740 x 614 x 640 = 124225658880000
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.
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
445 : 1, 5, 89, 445
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
614 : 1, 2, 307, 614
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 960,445,740,614,640, is 1.
Now, the common factors can be found like this.
960:2x 2x 2x 2x 2x 2x 3x 5
445:5x 89
740:2x 2x 5x 37
614:2x 307
640:2x 2x 2x 2x 2x 2x 2x 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 2x 2x 2x 5x 5x 5 = 64000
Therefore, the value for common factors is 64000.
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 = 124225658880000/(1x64000)
LCM = 124225658880000/64000
LCM = 1941025920
Thus, we can understand that the LCM of 960,445,740,614,640 is 1941025920.
