The LCM of 988,772,884,484 is 392236988.
Find LCM of 988,772,884,484 with Prime Factorization
| 2 | 988, 772, 884, 484 |
| 2 | 494, 386, 442, 242 |
| 13 | 247, 193, 221, 121 |
| 19, 193, 17, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 193 x 17 x 121 = 392236988
Therefore, the lowest common multiple of 988,772,884,484 is 392236988.
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 772 x 884 x 484 = 326341174016
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
772 : 1, 2, 4, 193, 386, 772
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,772,884,484, is 4.
Now, the common factors can be found like this.
988:2x 2x 13x 19
772:2x 2x 193
884:2x 2x 13x 17
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 2x 2x 2x 13 = 208
Therefore, the value for common factors is 208.
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 = 326341174016/(4x208)
LCM = 326341174016/832
LCM = 392236988
Thus, we can understand that the LCM of 988,772,884,484 is 392236988.
