Given numbers are 516,210,787,978,296
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 516,210,787,978,296 is 171439859640.
Find LCM of 516,210,787,978,296 with Prime Factorization
| 2 | 516, 210, 787, 978, 296 |
| 2 | 258, 105, 787, 489, 148 |
| 3 | 129, 105, 787, 489, 74 |
| 43, 35, 787, 163, 74 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 35 x 787 x 163 x 74 = 171439859640
Therefore, the lowest common multiple of 516,210,787,978,296 is 171439859640.
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.
516 x 210 x 787 x 978 x 296 = 24687339788160
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.
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
787 : 1, 787
978 : 1, 2, 3, 6, 163, 326, 489, 978
296 : 1, 2, 4, 8, 37, 74, 148, 296
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 516,210,787,978,296, is 1.
Now, the common factors can be found like this.
516:2x 2x 3x 43
210:2x 3x 5x 7
787:787
978:2x 3x 163
296:2x 2x 2x 37
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 24687339788160/(1x144)
LCM = 24687339788160/144
LCM = 171439859640
Thus, we can understand that the LCM of 516,210,787,978,296 is 171439859640.
