Given numbers are 989,388,912,388,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,388,912,388,247 is 1137381648.
Find LCM of 989,388,912,388,247 with Prime Factorization
| 2 | 989, 388, 912, 388, 247 |
| 2 | 989, 194, 456, 194, 247 |
| 19 | 989, 97, 228, 97, 247 |
| 97 | 989, 97, 12, 97, 13 |
| 989, 1, 12, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 97 x 989 x 1 x 12 x 1 x 13 = 1137381648
Therefore, the lowest common multiple of 989,388,912,388,247 is 1137381648.
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.
989 x 388 x 912 x 388 x 247 = 33539110036224
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.
989 : 1, 23, 43, 989
388 : 1, 2, 4, 97, 194, 388
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
388 : 1, 2, 4, 97, 194, 388
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,388,912,388,247, is 1.
Now, the common factors can be found like this.
989:23x 43
388:2x 2x 97
912:2x 2x 2x 2x 3x 19
388:2x 2x 97
247:13x 19
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 2x 2x 19x 97 = 29488
Therefore, the value for common factors is 29488.
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 = 33539110036224/(1x29488)
LCM = 33539110036224/29488
LCM = 1137381648
Thus, we can understand that the LCM of 989,388,912,388,247 is 1137381648.
