Given numbers are 132,989,100,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 132,989,100,731 is 55482900.
Find LCM of 132,989,100,731 with Prime Factorization
| 2 | 132, 989, 100, 731 |
| 2 | 66, 989, 50, 731 |
| 43 | 33, 989, 25, 731 |
| 33, 23, 25, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 33 x 23 x 25 x 17 = 55482900
Therefore, the lowest common multiple of 132,989,100,731 is 55482900.
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.
132 x 989 x 100 x 731 = 9543058800
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.
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
989 : 1, 23, 43, 989
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 132,989,100,731, is 1.
Now, the common factors can be found like this.
132:2x 2x 3x 11
989:23x 43
100:2x 2x 5x 5
731:17x 43
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 43 = 172
Therefore, the value for common factors is 172.
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 = 9543058800/(1x172)
LCM = 9543058800/172
LCM = 55482900
Thus, we can understand that the LCM of 132,989,100,731 is 55482900.
