Find LCM of 988,741,168,676,145 with Prime Factorization
| 2 | 988, 741, 168, 676, 145 |
| 2 | 494, 741, 84, 338, 145 |
| 3 | 247, 741, 42, 169, 145 |
| 13 | 247, 247, 14, 169, 145 |
| 19 | 19, 19, 14, 13, 145 |
| 1, 1, 14, 13, 145 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 19 x 1 x 1 x 14 x 13 x 145 = 78219960
Therefore, the lowest common multiple of 988,741,168,676,145 is 78219960.
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 741 x 168 x 676 x 145 = 12055885994880
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
741 : 1, 3, 13, 19, 39, 57, 247, 741
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
145 : 1, 5, 29, 145
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,741,168,676,145, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
741:3x 13x 19
168:2x 2x 2x 3x 7
676:2x 2x 13x 13
145:5x 29
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 3x 13x 13x 19 = 154128
Therefore, the value for common factors is 154128.
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 = 12055885994880/(1x154128)
LCM = 12055885994880/154128
LCM = 78219960
Thus, we can understand that the LCM of 988,741,168,676,145 is 78219960.
