Find LCM of 520,508,428,745,424 with Prime Factorization
| 2 | 520, 508, 428, 745, 424 |
| 2 | 260, 254, 214, 745, 212 |
| 2 | 130, 127, 107, 745, 106 |
| 5 | 65, 127, 107, 745, 53 |
| 13, 127, 107, 149, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 13 x 127 x 107 x 149 x 53 = 55802413160
Therefore, the lowest common multiple of 520,508,428,745,424 is 55802413160.
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.
520 x 508 x 428 x 745 x 424 = 35713544422400
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.
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
508 : 1, 2, 4, 127, 254, 508
428 : 1, 2, 4, 107, 214, 428
745 : 1, 5, 149, 745
424 : 1, 2, 4, 8, 53, 106, 212, 424
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,508,428,745,424, is 1.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
508:2x 2x 127
428:2x 2x 107
745:5x 149
424:2x 2x 2x 53
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 2x 2x 5 = 640
Therefore, the value for common factors is 640.
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 = 35713544422400/(1x640)
LCM = 35713544422400/640
LCM = 55802413160
Thus, we can understand that the LCM of 520,508,428,745,424 is 55802413160.
