The LCM of 511,803,990,847,688 is 1914287760.
Find LCM of 511,803,990,847,688 with Prime Factorization
| 2 | 511, 803, 990, 847, 688 |
| 7 | 511, 803, 495, 847, 344 |
| 11 | 73, 803, 495, 121, 344 |
| 73 | 73, 73, 45, 11, 344 |
| 1, 1, 45, 11, 344 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 73 x 1 x 1 x 45 x 11 x 344 = 1914287760
Therefore, the lowest common multiple of 511,803,990,847,688 is 1914287760.
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.
511 x 803 x 990 x 847 x 688 = 236724652977120
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.
511 : 1, 7, 73, 511
803 : 1, 11, 73, 803
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
847 : 1, 7, 11, 77, 121, 847
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 511,803,990,847,688, is 1.
Now, the common factors can be found like this.
511:7x 73
803:11x 73
990:2x 3x 3x 5x 11
847:7x 11x 11
688:2x 2x 2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11x 11x 73 = 123662
Therefore, the value for common factors is 123662.
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 = 236724652977120/(1x123662)
LCM = 236724652977120/123662
LCM = 1914287760
Thus, we can understand that the LCM of 511,803,990,847,688 is 1914287760.
