Given numbers are 640,981,100,195,229
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 640,981,100,195,229 is 9345398400.
Find LCM of 640,981,100,195,229 with Prime Factorization
| 2 | 640, 981, 100, 195, 229 |
| 2 | 320, 981, 50, 195, 229 |
| 3 | 160, 981, 25, 195, 229 |
| 5 | 160, 327, 25, 65, 229 |
| 32, 327, 5, 13, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 32 x 327 x 5 x 13 x 229 = 9345398400
Therefore, the lowest common multiple of 640,981,100,195,229 is 9345398400.
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.
640 x 981 x 100 x 195 x 229 = 2803619520000
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
981 : 1, 3, 9, 109, 327, 981
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
195 : 1, 3, 5, 13, 15, 39, 65, 195
229 : 1, 229
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,981,100,195,229, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
981:3x 3x 109
100:2x 2x 5x 5
195:3x 5x 13
229:229
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 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 2803619520000/(1x300)
LCM = 2803619520000/300
LCM = 9345398400
Thus, we can understand that the LCM of 640,981,100,195,229 is 9345398400.
