Find LCM of 504,905,918,856 with Prime Factorization
| 2 | 504, 905, 918, 856 |
| 2 | 252, 905, 459, 428 |
| 2 | 126, 905, 459, 214 |
| 3 | 63, 905, 459, 107 |
| 3 | 21, 905, 153, 107 |
| 7, 905, 51, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 7 x 905 x 51 x 107 = 2489046840
Therefore, the lowest common multiple of 504,905,918,856 is 2489046840.
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.
504 x 905 x 918 x 856 = 358422744960
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.
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
905 : 1, 5, 181, 905
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 504,905,918,856, is 1.
Now, the common factors can be found like this.
504:2x 2x 2x 3x 3x 7
905:5x 181
918:2x 3x 3x 3x 17
856:2x 2x 2x 107
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 3 = 144
Therefore, the value for common factors is 144.
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 = 358422744960/(1x144)
LCM = 358422744960/144
LCM = 2489046840
Thus, we can understand that the LCM of 504,905,918,856 is 2489046840.
