The LCM of 996,917,470,938,531 is 2545332984180.
Find LCM of 996,917,470,938,531 with Prime Factorization
| 2 | 996, 917, 470, 938, 531 |
| 3 | 498, 917, 235, 469, 531 |
| 7 | 166, 917, 235, 469, 177 |
| 166, 131, 235, 67, 177 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 166 x 131 x 235 x 67 x 177 = 2545332984180
Therefore, the lowest common multiple of 996,917,470,938,531 is 2545332984180.
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.
996 x 917 x 470 x 938 x 531 = 213807970671120
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.
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
917 : 1, 7, 131, 917
470 : 1, 2, 5, 10, 47, 94, 235, 470
938 : 1, 2, 7, 14, 67, 134, 469, 938
531 : 1, 3, 9, 59, 177, 531
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 996,917,470,938,531, is 1.
Now, the common factors can be found like this.
996:2x 2x 3x 83
917:7x 131
470:2x 5x 47
938:2x 7x 67
531:3x 3x 59
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 7 = 84
Therefore, the value for common factors is 84.
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 = 213807970671120/(1x84)
LCM = 213807970671120/84
LCM = 2545332984180
Thus, we can understand that the LCM of 996,917,470,938,531 is 2545332984180.
