The LCM of 989,287,242,484 is 137380012.
Find LCM of 989,287,242,484 with Prime Factorization
| 2 | 989, 287, 242, 484 |
| 11 | 989, 287, 121, 242 |
| 11 | 989, 287, 11, 22 |
| 989, 287, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 11 x 989 x 287 x 1 x 2 = 137380012
Therefore, the lowest common multiple of 989,287,242,484 is 137380012.
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 287 x 242 x 484 = 33245962904
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
287 : 1, 7, 41, 287
242 : 1, 2, 11, 22, 121, 242
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,287,242,484, is 1.
Now, the common factors can be found like this.
989:23x 43
287:7x 41
242:2x 11x 11
484:2x 2x 11x 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 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 33245962904/(1x242)
LCM = 33245962904/242
LCM = 137380012
Thus, we can understand that the LCM of 989,287,242,484 is 137380012.
