Find LCM of 315,921,791,940,538 with Prime Factorization
| 2 | 315, 921, 791, 940, 538 |
| 3 | 315, 921, 791, 470, 269 |
| 5 | 105, 307, 791, 470, 269 |
| 7 | 21, 307, 791, 94, 269 |
| 3, 307, 113, 94, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 3 x 307 x 113 x 94 x 269 = 552633874380
Therefore, the lowest common multiple of 315,921,791,940,538 is 552633874380.
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.
315 x 921 x 791 x 940 x 538 = 116053113619800
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
921 : 1, 3, 307, 921
791 : 1, 7, 113, 791
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
538 : 1, 2, 269, 538
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,921,791,940,538, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
921:3x 307
791:7x 113
940:2x 2x 5x 47
538:2x 269
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 116053113619800/(1x210)
LCM = 116053113619800/210
LCM = 552633874380
Thus, we can understand that the LCM of 315,921,791,940,538 is 552633874380.
