The LCM of 273,721,390,981,375 is 2298728250.
Find LCM of 273,721,390,981,375 with Prime Factorization
| 3 | 273, 721, 390, 981, 375 |
| 5 | 91, 721, 130, 327, 125 |
| 7 | 91, 721, 26, 327, 25 |
| 13 | 13, 103, 26, 327, 25 |
| 1, 103, 2, 327, 25 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 13 x 1 x 103 x 2 x 327 x 25 = 2298728250
Therefore, the lowest common multiple of 273,721,390,981,375 is 2298728250.
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.
273 x 721 x 390 x 981 x 375 = 28239876551250
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.
273 : 1, 3, 7, 13, 21, 39, 91, 273
721 : 1, 7, 103, 721
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
981 : 1, 3, 9, 109, 327, 981
375 : 1, 3, 5, 15, 25, 75, 125, 375
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 273,721,390,981,375, is 1.
Now, the common factors can be found like this.
273:3x 7x 13
721:7x 103
390:2x 3x 5x 13
981:3x 3x 109
375:3x 5x 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.
3x 3x 3x 5x 7x 13 = 12285
Therefore, the value for common factors is 12285.
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 = 28239876551250/(1x12285)
LCM = 28239876551250/12285
LCM = 2298728250
Thus, we can understand that the LCM of 273,721,390,981,375 is 2298728250.
