Given numbers are 981,737,969,320,330
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,737,969,320,330 is 74728969920.
Find LCM of 981,737,969,320,330 with Prime Factorization
| 2 | 981, 737, 969, 320, 330 |
| 3 | 981, 737, 969, 160, 165 |
| 5 | 327, 737, 323, 160, 55 |
| 11 | 327, 737, 323, 32, 11 |
| 327, 67, 323, 32, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 327 x 67 x 323 x 32 x 1 = 74728969920
Therefore, the lowest common multiple of 981,737,969,320,330 is 74728969920.
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 737 x 969 x 320 x 330 = 73981680220800
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
737 : 1, 11, 67, 737
969 : 1, 3, 17, 19, 51, 57, 323, 969
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,737,969,320,330, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
737:11x 67
969:3x 17x 19
320:2x 2x 2x 2x 2x 2x 5
330:2x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 11 = 990
Therefore, the value for common factors is 990.
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 = 73981680220800/(1x990)
LCM = 73981680220800/990
LCM = 74728969920
Thus, we can understand that the LCM of 981,737,969,320,330 is 74728969920.
