Given numbers are 459,631,490,788,969
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 459,631,490,788,969 is 1062399720060.
Find LCM of 459,631,490,788,969 with Prime Factorization
| 2 | 459, 631, 490, 788, 969 |
| 3 | 459, 631, 245, 394, 969 |
| 17 | 153, 631, 245, 394, 323 |
| 9, 631, 245, 394, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 9 x 631 x 245 x 394 x 19 = 1062399720060
Therefore, the lowest common multiple of 459,631,490,788,969 is 1062399720060.
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.
459 x 631 x 490 x 788 x 969 = 108364771446120
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.
459 : 1, 3, 9, 17, 27, 51, 153, 459
631 : 1, 631
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
788 : 1, 2, 4, 197, 394, 788
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 459,631,490,788,969, is 1.
Now, the common factors can be found like this.
459:3x 3x 3x 17
631:631
490:2x 5x 7x 7
788:2x 2x 197
969:3x 17x 19
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 17 = 102
Therefore, the value for common factors is 102.
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 = 108364771446120/(1x102)
LCM = 108364771446120/102
LCM = 1062399720060
Thus, we can understand that the LCM of 459,631,490,788,969 is 1062399720060.
