Given numbers are 514,530,720,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 514,530,720,981 is 1068976080.
Find LCM of 514,530,720,981 with Prime Factorization
| 2 | 514, 530, 720, 981 |
| 3 | 257, 265, 360, 981 |
| 3 | 257, 265, 120, 327 |
| 5 | 257, 265, 40, 109 |
| 257, 53, 8, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 257 x 53 x 8 x 109 = 1068976080
Therefore, the lowest common multiple of 514,530,720,981 is 1068976080.
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.
514 x 530 x 720 x 981 = 192415694400
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.
514 : 1, 2, 257, 514
530 : 1, 2, 5, 10, 53, 106, 265, 530
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 514,530,720,981, is 1.
Now, the common factors can be found like this.
514:2x 257
530:2x 5x 53
720:2x 2x 2x 2x 3x 3x 5
981:3x 3x 109
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 192415694400/(1x180)
LCM = 192415694400/180
LCM = 1068976080
Thus, we can understand that the LCM of 514,530,720,981 is 1068976080.
