Given numbers are 209,917,322,880
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,917,322,880 is 352641520.
Find LCM of 209,917,322,880 with Prime Factorization
| 2 | 209, 917, 322, 880 |
| 7 | 209, 917, 161, 440 |
| 11 | 209, 131, 23, 440 |
| 19, 131, 23, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 19 x 131 x 23 x 40 = 352641520
Therefore, the lowest common multiple of 209,917,322,880 is 352641520.
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.
209 x 917 x 322 x 880 = 54306794080
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.
209 : 1, 11, 19, 209
917 : 1, 7, 131, 917
322 : 1, 2, 7, 14, 23, 46, 161, 322
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,917,322,880, is 1.
Now, the common factors can be found like this.
209:11x 19
917:7x 131
322:2x 7x 23
880:2x 2x 2x 2x 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 7x 11 = 154
Therefore, the value for common factors is 154.
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 = 54306794080/(1x154)
LCM = 54306794080/154
LCM = 352641520
Thus, we can understand that the LCM of 209,917,322,880 is 352641520.
