The LCM of 924,242,390,484 is 660660.
Find LCM of 924,242,390,484 with Prime Factorization
| 2 | 924, 242, 390, 484 |
| 2 | 462, 121, 195, 242 |
| 3 | 231, 121, 195, 121 |
| 11 | 77, 121, 65, 121 |
| 11 | 7, 11, 65, 11 |
| 7, 1, 65, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 11 x 7 x 1 x 65 x 1 = 660660
Therefore, the lowest common multiple of 924,242,390,484 is 660660.
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.
924 x 242 x 390 x 484 = 42208246080
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.
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
242 : 1, 2, 11, 22, 121, 242
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 924,242,390,484, is 2.
Now, the common factors can be found like this.
924:2x 2x 3x 7x 11
242:2x 11x 11
390:2x 3x 5x 13
484:2x 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 3x 11x 11x 11 = 31944
Therefore, the value for common factors is 31944.
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 = 42208246080/(2x31944)
LCM = 42208246080/63888
LCM = 660660
Thus, we can understand that the LCM of 924,242,390,484 is 660660.
