The LCM of 913,721,990,927 is 59244570.
Find LCM of 913,721,990,927 with Prime Factorization
| 3 | 913, 721, 990, 927 |
| 3 | 913, 721, 330, 309 |
| 11 | 913, 721, 110, 103 |
| 103 | 83, 721, 10, 103 |
| 83, 7, 10, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 103 x 83 x 7 x 10 x 1 = 59244570
Therefore, the lowest common multiple of 913,721,990,927 is 59244570.
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.
913 x 721 x 990 x 927 = 604116880290
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.
913 : 1, 11, 83, 913
721 : 1, 7, 103, 721
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
927 : 1, 3, 9, 103, 309, 927
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 913,721,990,927, is 1.
Now, the common factors can be found like this.
913:11x 83
721:7x 103
990:2x 3x 3x 5x 11
927:3x 3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11x 103 = 10197
Therefore, the value for common factors is 10197.
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 = 604116880290/(1x10197)
LCM = 604116880290/10197
LCM = 59244570
Thus, we can understand that the LCM of 913,721,990,927 is 59244570.
