Find LCM of 305,660,754,889,561 with Prime Factorization
| 2 | 305, 660, 754, 889, 561 |
| 3 | 305, 330, 377, 889, 561 |
| 5 | 305, 110, 377, 889, 187 |
| 11 | 61, 22, 377, 889, 187 |
| 61, 2, 377, 889, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 61 x 2 x 377 x 889 x 17 = 229385416260
Therefore, the lowest common multiple of 305,660,754,889,561 is 229385416260.
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.
305 x 660 x 754 x 889 x 561 = 75697187365800
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.
305 : 1, 5, 61, 305
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
754 : 1, 2, 13, 26, 29, 58, 377, 754
889 : 1, 7, 127, 889
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,660,754,889,561, is 1.
Now, the common factors can be found like this.
305:5x 61
660:2x 2x 3x 5x 11
754:2x 13x 29
889:7x 127
561:3x 11x 17
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 5x 11 = 330
Therefore, the value for common factors is 330.
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 = 75697187365800/(1x330)
LCM = 75697187365800/330
LCM = 229385416260
Thus, we can understand that the LCM of 305,660,754,889,561 is 229385416260.
