Find LCM of 784,251,387,888,960 with Prime Factorization
| 2 | 784, 251, 387, 888, 960 |
| 2 | 392, 251, 387, 444, 480 |
| 2 | 196, 251, 387, 222, 240 |
| 2 | 98, 251, 387, 111, 120 |
| 3 | 49, 251, 387, 111, 60 |
| 49, 251, 129, 37, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 49 x 251 x 129 x 37 x 20 = 56355001920
Therefore, the lowest common multiple of 784,251,387,888,960 is 56355001920.
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.
784 x 251 x 387 x 888 x 960 = 64920962211840
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
251 : 1, 251
387 : 1, 3, 9, 43, 129, 387
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,251,387,888,960, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
251:251
387:3x 3x 43
888:2x 2x 2x 3x 37
960:2x 2x 2x 2x 2x 2x 3x 5
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 3x 3 = 1152
Therefore, the value for common factors is 1152.
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 = 64920962211840/(1x1152)
LCM = 64920962211840/1152
LCM = 56355001920
Thus, we can understand that the LCM of 784,251,387,888,960 is 56355001920.
