Find LCM of 664,728,664,487,416 with Prime Factorization
| 2 | 664, 728, 664, 487, 416 |
| 2 | 332, 364, 332, 487, 208 |
| 2 | 166, 182, 166, 487, 104 |
| 13 | 83, 91, 83, 487, 52 |
| 83 | 83, 7, 83, 487, 4 |
| 1, 7, 1, 487, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 83 x 1 x 7 x 1 x 487 x 4 = 117705952
Therefore, the lowest common multiple of 664,728,664,487,416 is 117705952.
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.
664 x 728 x 664 x 487 x 416 = 65026417770496
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.
664 : 1, 2, 4, 8, 83, 166, 332, 664
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
664 : 1, 2, 4, 8, 83, 166, 332, 664
487 : 1, 487
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,728,664,487,416, is 1.
Now, the common factors can be found like this.
664:2x 2x 2x 83
728:2x 2x 2x 7x 13
664:2x 2x 2x 83
487:487
416:2x 2x 2x 2x 2x 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 2x 2x 2x 2x 2x 13x 83 = 552448
Therefore, the value for common factors is 552448.
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 = 65026417770496/(1x552448)
LCM = 65026417770496/552448
LCM = 117705952
Thus, we can understand that the LCM of 664,728,664,487,416 is 117705952.
