Find LCM of 784,908,353,392 with Prime Factorization
| 2 | 784, 908, 353, 392 |
| 2 | 392, 454, 353, 196 |
| 2 | 98, 227, 353, 196 |
| 7 | 49, 227, 353, 98 |
| 7 | 7, 227, 353, 14 |
| 1, 227, 353, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 7 x 1 x 227 x 353 x 2 = 62822704
Therefore, the lowest common multiple of 784,908,353,392 is 62822704.
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 908 x 353 x 392 = 98505999872
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
908 : 1, 2, 4, 227, 454, 908
353 : 1, 353
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,908,353,392, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
908:2x 2x 227
353:353
392:2x 2x 2x 7x 7
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 7x 7 = 1568
Therefore, the value for common factors is 1568.
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 = 98505999872/(1x1568)
LCM = 98505999872/1568
LCM = 62822704
Thus, we can understand that the LCM of 784,908,353,392 is 62822704.
