Find LCM of 706,784,238,872,285 with Prime Factorization
| 2 | 706, 784, 238, 872, 285 |
| 2 | 353, 392, 119, 436, 285 |
| 2 | 353, 196, 119, 218, 285 |
| 7 | 353, 98, 119, 109, 285 |
| 353, 14, 17, 109, 285 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 353 x 14 x 17 x 109 x 285 = 146154114960
Therefore, the lowest common multiple of 706,784,238,872,285 is 146154114960.
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.
706 x 784 x 238 x 872 x 285 = 32738521751040
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.
706 : 1, 2, 353, 706
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
238 : 1, 2, 7, 14, 17, 34, 119, 238
872 : 1, 2, 4, 8, 109, 218, 436, 872
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 706,784,238,872,285, is 1.
Now, the common factors can be found like this.
706:2x 353
784:2x 2x 2x 2x 7x 7
238:2x 7x 17
872:2x 2x 2x 109
285:3x 5x 19
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 7 = 224
Therefore, the value for common factors is 224.
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 = 32738521751040/(1x224)
LCM = 32738521751040/224
LCM = 146154114960
Thus, we can understand that the LCM of 706,784,238,872,285 is 146154114960.
