The LCM of 782,728,200,585 is 64045800.
Find LCM of 782,728,200,585 with Prime Factorization
| 2 | 782, 728, 200, 585 |
| 2 | 391, 364, 100, 585 |
| 2 | 391, 182, 50, 585 |
| 5 | 391, 91, 25, 585 |
| 13 | 391, 91, 5, 117 |
| 391, 7, 5, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 13 x 391 x 7 x 5 x 9 = 64045800
Therefore, the lowest common multiple of 782,728,200,585 is 64045800.
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.
782 x 728 x 200 x 585 = 66607632000
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,728,200,585, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
728:2x 2x 2x 7x 13
200:2x 2x 2x 5x 5
585:3x 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 13 = 1040
Therefore, the value for common factors is 1040.
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 = 66607632000/(1x1040)
LCM = 66607632000/1040
LCM = 64045800
Thus, we can understand that the LCM of 782,728,200,585 is 64045800.
