Given numbers are 248,989,989,215
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 248,989,989,215 is 1226360.
Find LCM of 248,989,989,215 with Prime Factorization
| 23 | 248, 989, 989, 215 |
| 43 | 248, 43, 43, 215 |
| 248, 1, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
23 x 43 x 248 x 1 x 1 x 5 = 1226360
Therefore, the lowest common multiple of 248,989,989,215 is 1226360.
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.
248 x 989 x 989 x 215 = 52153411720
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.
248 : 1, 2, 4, 8, 31, 62, 124, 248
989 : 1, 23, 43, 989
989 : 1, 23, 43, 989
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,989,989,215, is 1.
Now, the common factors can be found like this.
248:2x 2x 2x 31
989:23x 43
989:23x 43
215:5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 43x 43 = 42527
Therefore, the value for common factors is 42527.
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 = 52153411720/(1x42527)
LCM = 52153411720/42527
LCM = 1226360
Thus, we can understand that the LCM of 248,989,989,215 is 1226360.
