Find LCM of 725,208,421,780,304 with Prime Factorization
| 2 | 725, 208, 421, 780, 304 |
| 2 | 725, 104, 421, 390, 152 |
| 2 | 725, 52, 421, 195, 76 |
| 2 | 725, 26, 421, 195, 38 |
| 5 | 725, 13, 421, 195, 19 |
| 13 | 145, 13, 421, 39, 19 |
| 145, 1, 421, 3, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 13 x 145 x 1 x 421 x 3 x 19 = 3618747600
Therefore, the lowest common multiple of 725,208,421,780,304 is 3618747600.
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.
725 x 208 x 421 x 780 x 304 = 15053990016000
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.
725 : 1, 5, 25, 29, 145, 725
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
421 : 1, 421
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
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,208,421,780,304, is 1.
Now, the common factors can be found like this.
725:5x 5x 29
208:2x 2x 2x 2x 13
421:421
780:2x 2x 3x 5x 13
304:2x 2x 2x 2x 19
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 5x 13 = 4160
Therefore, the value for common factors is 4160.
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 = 15053990016000/(1x4160)
LCM = 15053990016000/4160
LCM = 3618747600
Thus, we can understand that the LCM of 725,208,421,780,304 is 3618747600.
