Find LCM of 154,308,672,161,664 with Prime Factorization
| 2 | 154, 308, 672, 161, 664 |
| 2 | 77, 154, 336, 161, 332 |
| 2 | 77, 77, 168, 161, 166 |
| 7 | 77, 77, 84, 161, 83 |
| 11 | 11, 11, 12, 23, 83 |
| 1, 1, 12, 23, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 11 x 1 x 1 x 12 x 23 x 83 = 14111328
Therefore, the lowest common multiple of 154,308,672,161,664 is 14111328.
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.
154 x 308 x 672 x 161 x 664 = 3407490594816
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
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
161 : 1, 7, 23, 161
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,308,672,161,664, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
308:2x 2x 7x 11
672:2x 2x 2x 2x 2x 3x 7
161:7x 23
664:2x 2x 2x 83
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 7x 7x 7x 11 = 241472
Therefore, the value for common factors is 241472.
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 = 3407490594816/(1x241472)
LCM = 3407490594816/241472
LCM = 14111328
Thus, we can understand that the LCM of 154,308,672,161,664 is 14111328.
