Find LCM of 721,520,728,481,360 with Prime Factorization
| 2 | 721, 520, 728, 481, 360 |
| 2 | 721, 260, 364, 481, 180 |
| 2 | 721, 130, 182, 481, 90 |
| 5 | 721, 65, 91, 481, 45 |
| 7 | 721, 13, 91, 481, 9 |
| 13 | 103, 13, 13, 481, 9 |
| 103, 1, 1, 37, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 13 x 103 x 1 x 1 x 37 x 9 = 124848360
Therefore, the lowest common multiple of 721,520,728,481,360 is 124848360.
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.
721 x 520 x 728 x 481 x 360 = 47262595161600
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.
721 : 1, 7, 103, 721
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
481 : 1, 13, 37, 481
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,520,728,481,360, is 1.
Now, the common factors can be found like this.
721:7x 103
520:2x 2x 2x 5x 13
728:2x 2x 2x 7x 13
481:13x 37
360:2x 2x 2x 3x 3x 5
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 7x 13x 13 = 378560
Therefore, the value for common factors is 378560.
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 = 47262595161600/(1x378560)
LCM = 47262595161600/378560
LCM = 124848360
Thus, we can understand that the LCM of 721,520,728,481,360 is 124848360.
