The LCM of 289,396,753,291,220 is 13931840340.
Find LCM of 289,396,753,291,220 with Prime Factorization
| 2 | 289, 396, 753, 291, 220 |
| 2 | 289, 198, 753, 291, 110 |
| 3 | 289, 99, 753, 291, 55 |
| 11 | 289, 33, 251, 97, 55 |
| 289, 3, 251, 97, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 289 x 3 x 251 x 97 x 5 = 13931840340
Therefore, the lowest common multiple of 289,396,753,291,220 is 13931840340.
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.
289 x 396 x 753 x 291 x 220 = 5517008774640
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.
289 : 1, 17, 289
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
753 : 1, 3, 251, 753
291 : 1, 3, 97, 291
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,396,753,291,220, is 1.
Now, the common factors can be found like this.
289:17x 17
396:2x 2x 3x 3x 11
753:3x 251
291:3x 97
220:2x 2x 5x 11
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 3x 3x 11 = 396
Therefore, the value for common factors is 396.
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 = 5517008774640/(1x396)
LCM = 5517008774640/396
LCM = 13931840340
Thus, we can understand that the LCM of 289,396,753,291,220 is 13931840340.
