Given numbers are 987,906,542,910
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,906,542,910 is 5250573510.
Find LCM of 987,906,542,910 with Prime Factorization
| 2 | 987, 906, 542, 910 |
| 3 | 987, 453, 271, 455 |
| 7 | 329, 151, 271, 455 |
| 47, 151, 271, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 47 x 151 x 271 x 65 = 5250573510
Therefore, the lowest common multiple of 987,906,542,910 is 5250573510.
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.
987 x 906 x 542 x 910 = 441048174840
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
906 : 1, 2, 3, 6, 151, 302, 453, 906
542 : 1, 2, 271, 542
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,906,542,910, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
906:2x 3x 151
542:2x 271
910:2x 5x 7x 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 3x 7 = 84
Therefore, the value for common factors is 84.
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 = 441048174840/(1x84)
LCM = 441048174840/84
LCM = 5250573510
Thus, we can understand that the LCM of 987,906,542,910 is 5250573510.
