Find LCM of 640,262,893,992,288 with Prime Factorization
| 2 | 640, 262, 893, 992, 288 |
| 2 | 320, 131, 893, 496, 144 |
| 2 | 160, 131, 893, 248, 72 |
| 2 | 80, 131, 893, 124, 36 |
| 2 | 40, 131, 893, 62, 18 |
| 20, 131, 893, 31, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 20 x 131 x 893 x 31 x 9 = 20888484480
Therefore, the lowest common multiple of 640,262,893,992,288 is 20888484480.
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 262 x 893 x 992 x 288 = 42779616215040
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
262 : 1, 2, 131, 262
893 : 1, 19, 47, 893
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,262,893,992,288, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
262:2x 131
893:19x 47
992:2x 2x 2x 2x 2x 31
288:2x 2x 2x 2x 2x 3x 3
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 2x 2 = 2048
Therefore, the value for common factors is 2048.
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 = 42779616215040/(1x2048)
LCM = 42779616215040/2048
LCM = 20888484480
Thus, we can understand that the LCM of 640,262,893,992,288 is 20888484480.
