Find LCM of 988,559,946,728 with Prime Factorization
| 2 | 988, 559, 946, 728 |
| 2 | 494, 559, 473, 364 |
| 13 | 247, 559, 473, 182 |
| 43 | 19, 43, 473, 14 |
| 19, 1, 11, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 43 x 19 x 1 x 11 x 14 = 6542536
Therefore, the lowest common multiple of 988,559,946,728 is 6542536.
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 559 x 946 x 728 = 380356872896
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
559 : 1, 13, 43, 559
946 : 1, 2, 11, 22, 43, 86, 473, 946
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,559,946,728, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
559:13x 43
946:2x 11x 43
728:2x 2x 2x 7x 13
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 13x 13x 43 = 58136
Therefore, the value for common factors is 58136.
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 = 380356872896/(1x58136)
LCM = 380356872896/58136
LCM = 6542536
Thus, we can understand that the LCM of 988,559,946,728 is 6542536.
