The LCM of 668,320,751,800 is 200667200.
Find LCM of 668,320,751,800 with Prime Factorization
| 2 | 668, 320, 751, 800 |
| 2 | 334, 160, 751, 400 |
| 2 | 167, 80, 751, 200 |
| 2 | 167, 40, 751, 100 |
| 2 | 167, 20, 751, 50 |
| 5 | 167, 10, 751, 25 |
| 167, 2, 751, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 167 x 2 x 751 x 5 = 200667200
Therefore, the lowest common multiple of 668,320,751,800 is 200667200.
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.
668 x 320 x 751 x 800 = 128427008000
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.
668 : 1, 2, 4, 167, 334, 668
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
751 : 1, 751
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,320,751,800, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
320:2x 2x 2x 2x 2x 2x 5
751:751
800:2x 2x 2x 2x 2x 5x 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 5 = 640
Therefore, the value for common factors is 640.
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 = 128427008000/(1x640)
LCM = 128427008000/640
LCM = 200667200
Thus, we can understand that the LCM of 668,320,751,800 is 200667200.
