The LCM of 988,484,343,247 is 41004964.
Find LCM of 988,484,343,247 with Prime Factorization
| 2 | 988, 484, 343, 247 |
| 2 | 494, 242, 343, 247 |
| 13 | 247, 121, 343, 247 |
| 19 | 19, 121, 343, 19 |
| 1, 121, 343, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 1 x 121 x 343 x 1 = 41004964
Therefore, the lowest common multiple of 988,484,343,247 is 41004964.
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.
988 x 484 x 343 x 247 = 40512904432
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
343 : 1, 7, 49, 343
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,484,343,247, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
484:2x 2x 11x 11
343:7x 7x 7
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 13x 19 = 988
Therefore, the value for common factors is 988.
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 = 40512904432/(1x988)
LCM = 40512904432/988
LCM = 41004964
Thus, we can understand that the LCM of 988,484,343,247 is 41004964.
