Find LCM of 993,968,902,855,940 with Prime Factorization
| 2 | 993, 968, 902, 855, 940 |
| 2 | 993, 484, 451, 855, 470 |
| 3 | 993, 242, 451, 855, 235 |
| 5 | 331, 242, 451, 285, 235 |
| 11 | 331, 242, 451, 57, 47 |
| 331, 22, 41, 57, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 331 x 22 x 41 x 57 x 47 = 527899414680
Therefore, the lowest common multiple of 993,968,902,855,940 is 527899414680.
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.
993 x 968 x 902 x 855 x 940 = 696827227377600
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.
993 : 1, 3, 331, 993
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
902 : 1, 2, 11, 22, 41, 82, 451, 902
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,968,902,855,940, is 1.
Now, the common factors can be found like this.
993:3x 331
968:2x 2x 2x 11x 11
902:2x 11x 41
855:3x 3x 5x 19
940:2x 2x 5x 47
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 5x 11 = 1320
Therefore, the value for common factors is 1320.
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 = 696827227377600/(1x1320)
LCM = 696827227377600/1320
LCM = 527899414680
Thus, we can understand that the LCM of 993,968,902,855,940 is 527899414680.
