Given numbers are 721,778,273,756,227
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,778,273,756,227 is 89387714052.
Find LCM of 721,778,273,756,227 with Prime Factorization
| 2 | 721, 778, 273, 756, 227 |
| 3 | 721, 389, 273, 378, 227 |
| 7 | 721, 389, 91, 126, 227 |
| 103, 389, 13, 18, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 103 x 389 x 13 x 18 x 227 = 89387714052
Therefore, the lowest common multiple of 721,778,273,756,227 is 89387714052.
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 778 x 273 x 756 x 227 = 26279987931288
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
778 : 1, 2, 389, 778
273 : 1, 3, 7, 13, 21, 39, 91, 273
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
227 : 1, 227
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,778,273,756,227, is 1.
Now, the common factors can be found like this.
721:7x 103
778:2x 389
273:3x 7x 13
756:2x 2x 3x 3x 3x 7
227:227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 7 = 294
Therefore, the value for common factors is 294.
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 = 26279987931288/(1x294)
LCM = 26279987931288/294
LCM = 89387714052
Thus, we can understand that the LCM of 721,778,273,756,227 is 89387714052.
