Find LCM of 640,467,663,578,296 with Prime Factorization
| 2 | 640, 467, 663, 578, 296 |
| 2 | 320, 467, 663, 289, 148 |
| 2 | 160, 467, 663, 289, 74 |
| 17 | 80, 467, 663, 289, 37 |
| 80, 467, 39, 17, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 80 x 467 x 39 x 17 x 37 = 124641029760
Therefore, the lowest common multiple of 640,467,663,578,296 is 124641029760.
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.
640 x 467 x 663 x 578 x 296 = 33902360094720
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
467 : 1, 467
663 : 1, 3, 13, 17, 39, 51, 221, 663
578 : 1, 2, 17, 34, 289, 578
296 : 1, 2, 4, 8, 37, 74, 148, 296
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,467,663,578,296, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
467:467
663:3x 13x 17
578:2x 17x 17
296:2x 2x 2x 37
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 17 = 272
Therefore, the value for common factors is 272.
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 = 33902360094720/(1x272)
LCM = 33902360094720/272
LCM = 124641029760
Thus, we can understand that the LCM of 640,467,663,578,296 is 124641029760.
