Find LCM of 189,548,189,894 with Prime Factorization
| 2 | 189, 548, 189, 894 |
| 3 | 189, 274, 189, 447 |
| 3 | 63, 274, 63, 149 |
| 3 | 21, 274, 21, 149 |
| 7 | 7, 274, 7, 149 |
| 1, 274, 1, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 1 x 274 x 1 x 149 = 15432228
Therefore, the lowest common multiple of 189,548,189,894 is 15432228.
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.
189 x 548 x 189 x 894 = 17500146552
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
548 : 1, 2, 4, 137, 274, 548
189 : 1, 3, 7, 9, 21, 27, 63, 189
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,548,189,894, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
548:2x 2x 137
189:3x 3x 3x 7
894:2x 3x 149
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 3x 7 = 1134
Therefore, the value for common factors is 1134.
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 = 17500146552/(1x1134)
LCM = 17500146552/1134
LCM = 15432228
Thus, we can understand that the LCM of 189,548,189,894 is 15432228.
