Find LCM of 272,789,957,731,220 with Prime Factorization
| 2 | 272, 789, 957, 731, 220 |
| 2 | 136, 789, 957, 731, 110 |
| 3 | 68, 789, 957, 731, 55 |
| 11 | 68, 263, 319, 731, 55 |
| 17 | 68, 263, 29, 731, 5 |
| 4, 263, 29, 43, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 17 x 4 x 263 x 29 x 43 x 5 = 14718889680
Therefore, the lowest common multiple of 272,789,957,731,220 is 14718889680.
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.
272 x 789 x 957 x 731 x 220 = 33029188441920
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.
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
789 : 1, 3, 263, 789
957 : 1, 3, 11, 29, 33, 87, 319, 957
731 : 1, 17, 43, 731
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 272,789,957,731,220, is 1.
Now, the common factors can be found like this.
272:2x 2x 2x 2x 17
789:3x 263
957:3x 11x 29
731:17x 43
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 11x 17 = 2244
Therefore, the value for common factors is 2244.
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 = 33029188441920/(1x2244)
LCM = 33029188441920/2244
LCM = 14718889680
Thus, we can understand that the LCM of 272,789,957,731,220 is 14718889680.
