Given numbers are 649,286,364,904
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,286,364,904 is 53389336.
Find LCM of 649,286,364,904 with Prime Factorization
| 2 | 649, 286, 364, 904 |
| 2 | 649, 143, 182, 452 |
| 11 | 649, 143, 91, 226 |
| 13 | 59, 13, 91, 226 |
| 59, 1, 7, 226 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 13 x 59 x 1 x 7 x 226 = 53389336
Therefore, the lowest common multiple of 649,286,364,904 is 53389336.
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.
649 x 286 x 364 x 904 = 61077400384
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.
649 : 1, 11, 59, 649
286 : 1, 2, 11, 13, 22, 26, 143, 286
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
904 : 1, 2, 4, 8, 113, 226, 452, 904
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,286,364,904, is 1.
Now, the common factors can be found like this.
649:11x 59
286:2x 11x 13
364:2x 2x 7x 13
904:2x 2x 2x 113
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 11x 13 = 1144
Therefore, the value for common factors is 1144.
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 = 61077400384/(1x1144)
LCM = 61077400384/1144
LCM = 53389336
Thus, we can understand that the LCM of 649,286,364,904 is 53389336.
