The LCM of 990,905,870,882 is 254628990.
Find LCM of 990,905,870,882 with Prime Factorization
2 | 990, 905, 870, 882 |
3 | 495, 905, 435, 441 |
3 | 165, 905, 145, 147 |
5 | 55, 905, 145, 49 |
11, 181, 29, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 181 x 29 x 49 = 254628990
Therefore, the lowest common multiple of 990,905,870,882 is 254628990.
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.
990 x 905 x 870 x 882 = 687498273000
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.
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
905 : 1, 5, 181, 905
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,905,870,882, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
905:5x 181
870:2x 3x 5x 29
882:2x 3x 3x 7x 7
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 3x 3x 3x 5x 5 = 2700
Therefore, the value for common factors is 2700.
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 = 687498273000/(1x2700)
LCM = 687498273000/2700
LCM = 254628990
Thus, we can understand that the LCM of 990,905,870,882 is 254628990.
