Find LCM of 520,484,299,780 with Prime Factorization
| 2 | 520, 484, 299, 780 |
| 2 | 260, 242, 299, 390 |
| 5 | 130, 121, 299, 195 |
| 13 | 26, 121, 299, 39 |
| 2, 121, 23, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 2 x 121 x 23 x 3 = 4341480
Therefore, the lowest common multiple of 520,484,299,780 is 4341480.
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 484 x 299 x 780 = 58696809600
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
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
299 : 1, 13, 23, 299
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,484,299,780, is 1.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
484:2x 2x 11x 11
299:13x 23
780:2x 2x 3x 5x 13
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 5x 13x 13 = 13520
Therefore, the value for common factors is 13520.
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 = 58696809600/(1x13520)
LCM = 58696809600/13520
LCM = 4341480
Thus, we can understand that the LCM of 520,484,299,780 is 4341480.
