Find LCM of 504,755,728,390,934 with Prime Factorization
| 2 | 504, 755, 728, 390, 934 |
| 2 | 252, 755, 364, 195, 467 |
| 2 | 126, 755, 182, 195, 467 |
| 3 | 63, 755, 91, 195, 467 |
| 5 | 21, 755, 91, 65, 467 |
| 7 | 21, 151, 91, 13, 467 |
| 13 | 3, 151, 13, 13, 467 |
| 3, 151, 1, 1, 467 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 13 x 3 x 151 x 1 x 1 x 467 = 2310136920
Therefore, the lowest common multiple of 504,755,728,390,934 is 2310136920.
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.
504 x 755 x 728 x 390 x 934 = 100906780665600
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.
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
755 : 1, 5, 151, 755
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
934 : 1, 2, 467, 934
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 504,755,728,390,934, is 1.
Now, the common factors can be found like this.
504:2x 2x 2x 3x 3x 7
755:5x 151
728:2x 2x 2x 7x 13
390:2x 3x 5x 13
934:2x 467
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 2x 2x 3x 5x 7x 13 = 43680
Therefore, the value for common factors is 43680.
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 = 100906780665600/(1x43680)
LCM = 100906780665600/43680
LCM = 2310136920
Thus, we can understand that the LCM of 504,755,728,390,934 is 2310136920.
