The LCM of 242,438,116,979,141 is 12858056772.
Find LCM of 242,438,116,979,141 with Prime Factorization
| 2 | 242, 438, 116, 979, 141 |
| 3 | 121, 219, 58, 979, 141 |
| 11 | 121, 73, 58, 979, 47 |
| 11, 73, 58, 89, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 11 x 73 x 58 x 89 x 47 = 12858056772
Therefore, the lowest common multiple of 242,438,116,979,141 is 12858056772.
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.
242 x 438 x 116 x 979 x 141 = 1697263493904
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.
242 : 1, 2, 11, 22, 121, 242
438 : 1, 2, 3, 6, 73, 146, 219, 438
116 : 1, 2, 4, 29, 58, 116
979 : 1, 11, 89, 979
141 : 1, 3, 47, 141
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,438,116,979,141, is 1.
Now, the common factors can be found like this.
242:2x 11x 11
438:2x 3x 73
116:2x 2x 29
979:11x 89
141:3x 47
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 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 1697263493904/(1x132)
LCM = 1697263493904/132
LCM = 12858056772
Thus, we can understand that the LCM of 242,438,116,979,141 is 12858056772.
