Find LCM of 222,308,638,288,968 with Prime Factorization
| 2 | 222, 308, 638, 288, 968 |
| 2 | 111, 154, 319, 144, 484 |
| 2 | 111, 77, 319, 72, 242 |
| 3 | 111, 77, 319, 36, 121 |
| 11 | 37, 77, 319, 12, 121 |
| 37, 7, 29, 12, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 37 x 7 x 29 x 12 x 11 = 261743328
Therefore, the lowest common multiple of 222,308,638,288,968 is 261743328.
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.
222 x 308 x 638 x 288 x 968 = 12161641992192
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.
222 : 1, 2, 3, 6, 37, 74, 111, 222
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
638 : 1, 2, 11, 22, 29, 58, 319, 638
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 222,308,638,288,968, is 2.
Now, the common factors can be found like this.
222:2x 3x 37
308:2x 2x 7x 11
638:2x 11x 29
288:2x 2x 2x 2x 2x 3x 3
968:2x 2x 2x 11x 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 2x 2x 2x 2x 3x 11x 11 = 23232
Therefore, the value for common factors is 23232.
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 = 12161641992192/(2x23232)
LCM = 12161641992192/46464
LCM = 261743328
Thus, we can understand that the LCM of 222,308,638,288,968 is 261743328.
