Find LCM of 222,720,504,378 with Prime Factorization
| 2 | 222, 720, 504, 378 |
| 2 | 111, 360, 252, 189 |
| 2 | 111, 180, 126, 189 |
| 3 | 111, 90, 63, 189 |
| 3 | 37, 30, 21, 63 |
| 7 | 37, 10, 7, 21 |
| 37, 10, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 7 x 37 x 10 x 1 x 3 = 559440
Therefore, the lowest common multiple of 222,720,504,378 is 559440.
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 720 x 504 x 378 = 30451438080
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
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
6 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 222,720,504,378, is 6.
Now, the common factors can be found like this.
222:2x 3x 37
720:2x 2x 2x 2x 3x 3x 5
504:2x 2x 2x 3x 3x 7
378:2x 3x 3x 3x 7
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 3x 3x 3x 3x 7 = 9072
Therefore, the value for common factors is 9072.
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 = 30451438080/(6x9072)
LCM = 30451438080/54432
LCM = 559440
Thus, we can understand that the LCM of 222,720,504,378 is 559440.
