Find LCM of 455,340,988,217,188 with Prime Factorization
| 2 | 455, 340, 988, 217, 188 |
| 2 | 455, 170, 494, 217, 94 |
| 5 | 455, 85, 247, 217, 47 |
| 7 | 91, 17, 247, 217, 47 |
| 13 | 13, 17, 247, 31, 47 |
| 1, 17, 19, 31, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 13 x 1 x 17 x 19 x 31 x 47 = 856512020
Therefore, the lowest common multiple of 455,340,988,217,188 is 856512020.
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.
455 x 340 x 988 x 217 x 188 = 6235407505600
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
217 : 1, 7, 31, 217
188 : 1, 2, 4, 47, 94, 188
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,340,988,217,188, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
340:2x 2x 5x 17
988:2x 2x 13x 19
217:7x 31
188:2x 2x 47
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 2x 2x 5x 7x 13 = 7280
Therefore, the value for common factors is 7280.
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 = 6235407505600/(1x7280)
LCM = 6235407505600/7280
LCM = 856512020
Thus, we can understand that the LCM of 455,340,988,217,188 is 856512020.
