Given numbers are 981,542,110,637
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,542,110,637 is 18628179570.
Find LCM of 981,542,110,637 with Prime Factorization
| 2 | 981, 542, 110, 637 |
| 981, 271, 55, 637 |
Multiply the prime numbers at the bottom and the left side.
2 x 981 x 271 x 55 x 637 = 18628179570
Therefore, the lowest common multiple of 981,542,110,637 is 18628179570.
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.
981 x 542 x 110 x 637 = 37256359140
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.
981 : 1, 3, 9, 109, 327, 981
542 : 1, 2, 271, 542
110 : 1, 2, 5, 10, 11, 22, 55, 110
637 : 1, 7, 13, 49, 91, 637
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,542,110,637, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
542:2x 271
110:2x 5x 11
637:7x 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.
2 = 2
Therefore, the value for common factors is 2.
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 = 37256359140/(1x2)
LCM = 37256359140/2
LCM = 18628179570
Thus, we can understand that the LCM of 981,542,110,637 is 18628179570.
