Given numbers are 981,589,665,448
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,589,665,448 is 1294292160.
Find LCM of 981,589,665,448 with Prime Factorization
7 | 981, 589, 665, 448 |
19 | 981, 589, 95, 64 |
981, 31, 5, 64 |
Multiply the prime numbers at the bottom and the left side.
7 x 19 x 981 x 31 x 5 x 64 = 1294292160
Therefore, the lowest common multiple of 981,589,665,448 is 1294292160.
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 589 x 665 x 448 = 172140857280
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
589 : 1, 19, 31, 589
665 : 1, 5, 7, 19, 35, 95, 133, 665
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,589,665,448, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
589:19x 31
665:5x 7x 19
448:2x 2x 2x 2x 2x 2x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 19 = 133
Therefore, the value for common factors is 133.
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 = 172140857280/(1x133)
LCM = 172140857280/133
LCM = 1294292160
Thus, we can understand that the LCM of 981,589,665,448 is 1294292160.
