Find LCM of 654,490,168,872,193 with Prime Factorization
| 2 | 654, 490, 168, 872, 193 |
| 2 | 327, 245, 84, 436, 193 |
| 2 | 327, 245, 42, 218, 193 |
| 3 | 327, 245, 21, 109, 193 |
| 7 | 109, 245, 7, 109, 193 |
| 109 | 109, 35, 1, 109, 193 |
| 1, 35, 1, 1, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 109 x 1 x 35 x 1 x 1 x 193 = 123697560
Therefore, the lowest common multiple of 654,490,168,872,193 is 123697560.
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.
654 x 490 x 168 x 872 x 193 = 9060598874880
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
872 : 1, 2, 4, 8, 109, 218, 436, 872
193 : 1, 193
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,490,168,872,193, is 1.
Now, the common factors can be found like this.
654:2x 3x 109
490:2x 5x 7x 7
168:2x 2x 2x 3x 7
872:2x 2x 2x 109
193:193
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 2x 3x 7x 109 = 73248
Therefore, the value for common factors is 73248.
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 = 9060598874880/(1x73248)
LCM = 9060598874880/73248
LCM = 123697560
Thus, we can understand that the LCM of 654,490,168,872,193 is 123697560.
