The LCM of 289,222,949,420,658 is 200314749180.
Find LCM of 289,222,949,420,658 with Prime Factorization
| 2 | 289, 222, 949, 420, 658 |
| 3 | 289, 111, 949, 210, 329 |
| 7 | 289, 37, 949, 70, 329 |
| 289, 37, 949, 10, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 289 x 37 x 949 x 10 x 47 = 200314749180
Therefore, the lowest common multiple of 289,222,949,420,658 is 200314749180.
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.
289 x 222 x 949 x 420 x 658 = 16826438931120
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.
289 : 1, 17, 289
222 : 1, 2, 3, 6, 37, 74, 111, 222
949 : 1, 13, 73, 949
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
658 : 1, 2, 7, 14, 47, 94, 329, 658
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 289,222,949,420,658, is 1.
Now, the common factors can be found like this.
289:17x 17
222:2x 3x 37
949:13x 73
420:2x 2x 3x 5x 7
658:2x 7x 47
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 7 = 84
Therefore, the value for common factors is 84.
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 = 16826438931120/(1x84)
LCM = 16826438931120/84
LCM = 200314749180
Thus, we can understand that the LCM of 289,222,949,420,658 is 200314749180.
