Find LCM of 107,641,800,640 with Prime Factorization
| 2 | 107, 641, 800, 640 |
| 2 | 107, 641, 400, 320 |
| 2 | 107, 641, 200, 160 |
| 2 | 107, 641, 100, 80 |
| 2 | 107, 641, 50, 40 |
| 5 | 107, 641, 25, 20 |
| 107, 641, 5, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 107 x 641 x 5 x 4 = 219478400
Therefore, the lowest common multiple of 107,641,800,640 is 219478400.
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.
107 x 641 x 800 x 640 = 35116544000
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.
107 : 1, 107
641 : 1, 641
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
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 107,641,800,640, is 1.
Now, the common factors can be found like this.
107:107
641:641
800:2x 2x 2x 2x 2x 5x 5
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 5 = 160
Therefore, the value for common factors is 160.
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 = 35116544000/(1x160)
LCM = 35116544000/160
LCM = 219478400
Thus, we can understand that the LCM of 107,641,800,640 is 219478400.
