Find LCM of 907,686,672,256 with Prime Factorization
| 2 | 907, 686, 672, 256 |
| 2 | 907, 343, 336, 128 |
| 2 | 907, 343, 168, 64 |
| 2 | 907, 343, 84, 32 |
| 2 | 907, 343, 42, 16 |
| 7 | 907, 343, 21, 8 |
| 907, 49, 3, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 7 x 907 x 49 x 3 x 8 = 238925568
Therefore, the lowest common multiple of 907,686,672,256 is 238925568.
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.
907 x 686 x 672 x 256 = 107038654464
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.
907 : 1, 907
686 : 1, 2, 7, 14, 49, 98, 343, 686
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 907,686,672,256, is 1.
Now, the common factors can be found like this.
907:907
686:2x 7x 7x 7
672:2x 2x 2x 2x 2x 3x 7
256:2x 2x 2x 2x 2x 2x 2x 2
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 7 = 448
Therefore, the value for common factors is 448.
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 = 107038654464/(1x448)
LCM = 107038654464/448
LCM = 238925568
Thus, we can understand that the LCM of 907,686,672,256 is 238925568.
