Find LCM of 784,480,218,484,258 with Prime Factorization
| 2 | 784, 480, 218, 484, 258 |
| 2 | 392, 240, 109, 242, 129 |
| 2 | 196, 120, 109, 121, 129 |
| 2 | 98, 60, 109, 121, 129 |
| 3 | 49, 30, 109, 121, 129 |
| 49, 10, 109, 121, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 49 x 10 x 109 x 121 x 43 = 13338827040
Therefore, the lowest common multiple of 784,480,218,484,258 is 13338827040.
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.
784 x 480 x 218 x 484 x 258 = 10244219166720
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
218 : 1, 2, 109, 218
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
258 : 1, 2, 3, 6, 43, 86, 129, 258
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,480,218,484,258, is 2.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
480:2x 2x 2x 2x 2x 3x 5
218:2x 109
484:2x 2x 11x 11
258:2x 3x 43
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 2x 2x 2x 3 = 384
Therefore, the value for common factors is 384.
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 = 10244219166720/(2x384)
LCM = 10244219166720/768
LCM = 13338827040
Thus, we can understand that the LCM of 784,480,218,484,258 is 13338827040.
