Given numbers are 904,741,154,902,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 904,741,154,902,990 is 31721409720.
Find LCM of 904,741,154,902,990 with Prime Factorization
| 2 | 904, 741, 154, 902, 990 |
| 3 | 452, 741, 77, 451, 495 |
| 11 | 452, 247, 77, 451, 165 |
| 452, 247, 7, 41, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 452 x 247 x 7 x 41 x 15 = 31721409720
Therefore, the lowest common multiple of 904,741,154,902,990 is 31721409720.
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.
904 x 741 x 154 x 902 x 990 = 92118973826880
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.
904 : 1, 2, 4, 8, 113, 226, 452, 904
741 : 1, 3, 13, 19, 39, 57, 247, 741
154 : 1, 2, 7, 11, 14, 22, 77, 154
902 : 1, 2, 11, 22, 41, 82, 451, 902
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 904,741,154,902,990, is 1.
Now, the common factors can be found like this.
904:2x 2x 2x 113
741:3x 13x 19
154:2x 7x 11
902:2x 11x 41
990:2x 3x 3x 5x 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 11 = 2904
Therefore, the value for common factors is 2904.
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 = 92118973826880/(1x2904)
LCM = 92118973826880/2904
LCM = 31721409720
Thus, we can understand that the LCM of 904,741,154,902,990 is 31721409720.
