Find LCM of 647,452,856,915,585 with Prime Factorization
| 2 | 647, 452, 856, 915, 585 |
| 2 | 647, 226, 428, 915, 585 |
| 3 | 647, 113, 214, 915, 585 |
| 5 | 647, 113, 214, 305, 195 |
| 647, 113, 214, 61, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 647 x 113 x 214 x 61 x 39 = 2233274925960
Therefore, the lowest common multiple of 647,452,856,915,585 is 2233274925960.
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.
647 x 452 x 856 x 915 x 585 = 133996495557600
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.
647 : 1, 647
452 : 1, 2, 4, 113, 226, 452
856 : 1, 2, 4, 8, 107, 214, 428, 856
915 : 1, 3, 5, 15, 61, 183, 305, 915
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 647,452,856,915,585, is 1.
Now, the common factors can be found like this.
647:647
452:2x 2x 113
856:2x 2x 2x 107
915:3x 5x 61
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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 133996495557600/(1x60)
LCM = 133996495557600/60
LCM = 2233274925960
Thus, we can understand that the LCM of 647,452,856,915,585 is 2233274925960.
