The LCM of 520,764,385,768,900 is 11012601600.
Find LCM of 520,764,385,768,900 with Prime Factorization
| 2 | 520, 764, 385, 768, 900 |
| 2 | 260, 382, 385, 384, 450 |
| 2 | 130, 191, 385, 192, 225 |
| 3 | 65, 191, 385, 96, 225 |
| 5 | 65, 191, 385, 32, 75 |
| 13, 191, 77, 32, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 13 x 191 x 77 x 32 x 15 = 11012601600
Therefore, the lowest common multiple of 520,764,385,768,900 is 11012601600.
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.
520 x 764 x 385 x 768 x 900 = 105720975360000
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.
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
764 : 1, 2, 4, 191, 382, 764
385 : 1, 5, 7, 11, 35, 55, 77, 385
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,764,385,768,900, is 1.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
764:2x 2x 191
385:5x 7x 11
768:2x 2x 2x 2x 2x 2x 2x 2x 3
900:2x 2x 3x 3x 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 3x 5x 5 = 9600
Therefore, the value for common factors is 9600.
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 = 105720975360000/(1x9600)
LCM = 105720975360000/9600
LCM = 11012601600
Thus, we can understand that the LCM of 520,764,385,768,900 is 11012601600.
