Find LCM of 672,678,688,388,526 with Prime Factorization
| 2 | 672, 678, 688, 388, 526 |
| 2 | 336, 339, 344, 194, 263 |
| 2 | 168, 339, 172, 97, 263 |
| 2 | 84, 339, 86, 97, 263 |
| 3 | 42, 339, 43, 97, 263 |
| 14, 113, 43, 97, 263 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 14 x 113 x 43 x 97 x 263 = 83299741728
Therefore, the lowest common multiple of 672,678,688,388,526 is 83299741728.
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.
672 x 678 x 688 x 388 x 526 = 63974201647104
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.
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
678 : 1, 2, 3, 6, 113, 226, 339, 678
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
388 : 1, 2, 4, 97, 194, 388
526 : 1, 2, 263, 526
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,678,688,388,526, is 2.
Now, the common factors can be found like this.
672:2x 2x 2x 2x 2x 3x 7
678:2x 3x 113
688:2x 2x 2x 2x 43
388:2x 2x 97
526:2x 263
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 3 = 384
Therefore, the value for common factors is 384.
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 = 63974201647104/(2x384)
LCM = 63974201647104/768
LCM = 83299741728
Thus, we can understand that the LCM of 672,678,688,388,526 is 83299741728.
