Given numbers are 722,195,951,196,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,195,951,196,990 is 144334810620.
Find LCM of 722,195,951,196,990 with Prime Factorization
| 2 | 722, 195, 951, 196, 990 |
| 3 | 361, 195, 951, 98, 495 |
| 5 | 361, 65, 317, 98, 165 |
| 361, 13, 317, 98, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 361 x 13 x 317 x 98 x 33 = 144334810620
Therefore, the lowest common multiple of 722,195,951,196,990 is 144334810620.
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.
722 x 195 x 951 x 196 x 990 = 25980265911600
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.
722 : 1, 2, 19, 38, 361, 722
195 : 1, 3, 5, 13, 15, 39, 65, 195
951 : 1, 3, 317, 951
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,195,951,196,990, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
195:3x 5x 13
951:3x 317
196:2x 2x 7x 7
990:2x 3x 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 2x 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 25980265911600/(1x180)
LCM = 25980265911600/180
LCM = 144334810620
Thus, we can understand that the LCM of 722,195,951,196,990 is 144334810620.
