Given numbers are 904,990,985,988,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 904,990,985,988,856 is 2329810437240.
Find LCM of 904,990,985,988,856 with Prime Factorization
| 2 | 904, 990, 985, 988, 856 |
| 2 | 452, 495, 985, 494, 428 |
| 2 | 226, 495, 985, 247, 214 |
| 5 | 113, 495, 985, 247, 107 |
| 113, 99, 197, 247, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 113 x 99 x 197 x 247 x 107 = 2329810437240
Therefore, the lowest common multiple of 904,990,985,988,856 is 2329810437240.
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 990 x 985 x 988 x 856 = 745539339916800
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
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
985 : 1, 5, 197, 985
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
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 904,990,985,988,856, is 1.
Now, the common factors can be found like this.
904:2x 2x 2x 113
990:2x 3x 3x 5x 11
985:5x 197
988:2x 2x 13x 19
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 2x 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 745539339916800/(1x320)
LCM = 745539339916800/320
LCM = 2329810437240
Thus, we can understand that the LCM of 904,990,985,988,856 is 2329810437240.
