Find LCM of 902,422,897,832,990 with Prime Factorization
| 2 | 902, 422, 897, 832, 990 |
| 3 | 451, 211, 897, 416, 495 |
| 11 | 451, 211, 299, 416, 165 |
| 13 | 41, 211, 299, 416, 15 |
| 41, 211, 23, 32, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 41 x 211 x 23 x 32 x 15 = 81945040320
Therefore, the lowest common multiple of 902,422,897,832,990 is 81945040320.
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.
902 x 422 x 897 x 832 x 990 = 281235378378240
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
422 : 1, 2, 211, 422
897 : 1, 3, 13, 23, 39, 69, 299, 897
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
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 902,422,897,832,990, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
422:2x 211
897:3x 13x 23
832:2x 2x 2x 2x 2x 2x 13
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 13 = 3432
Therefore, the value for common factors is 3432.
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 = 281235378378240/(1x3432)
LCM = 281235378378240/3432
LCM = 81945040320
Thus, we can understand that the LCM of 902,422,897,832,990 is 81945040320.
