Find LCM of 298,686,447,927,189 with Prime Factorization
| 2 | 298, 686, 447, 927, 189 |
| 3 | 149, 343, 447, 927, 189 |
| 3 | 149, 343, 149, 309, 63 |
| 7 | 149, 343, 149, 103, 21 |
| 149 | 149, 49, 149, 103, 3 |
| 1, 49, 1, 103, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 149 x 1 x 49 x 1 x 103 x 3 = 284257134
Therefore, the lowest common multiple of 298,686,447,927,189 is 284257134.
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.
298 x 686 x 447 x 927 x 189 = 16009930301148
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.
298 : 1, 2, 149, 298
686 : 1, 2, 7, 14, 49, 98, 343, 686
447 : 1, 3, 149, 447
927 : 1, 3, 9, 103, 309, 927
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,686,447,927,189, is 1.
Now, the common factors can be found like this.
298:2x 149
686:2x 7x 7x 7
447:3x 149
927:3x 3x 103
189:3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7x 149 = 56322
Therefore, the value for common factors is 56322.
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 = 16009930301148/(1x56322)
LCM = 16009930301148/56322
LCM = 284257134
Thus, we can understand that the LCM of 298,686,447,927,189 is 284257134.
