The LCM of 721,788,294,468 is 465313212.
Find LCM of 721,788,294,468 with Prime Factorization
| 2 | 721, 788, 294, 468 |
| 2 | 721, 394, 147, 234 |
| 3 | 721, 197, 147, 117 |
| 7 | 721, 197, 49, 39 |
| 103, 197, 7, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 103 x 197 x 7 x 39 = 465313212
Therefore, the lowest common multiple of 721,788,294,468 is 465313212.
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.
721 x 788 x 294 x 468 = 78172619616
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.
721 : 1, 7, 103, 721
788 : 1, 2, 4, 197, 394, 788
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,788,294,468, is 1.
Now, the common factors can be found like this.
721:7x 103
788:2x 2x 197
294:2x 3x 7x 7
468:2x 2x 3x 3x 13
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 78172619616/(1x168)
LCM = 78172619616/168
LCM = 465313212
Thus, we can understand that the LCM of 721,788,294,468 is 465313212.
