Given numbers are 680,880,232,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 680,880,232,981 is 425597040.
Find LCM of 680,880,232,981 with Prime Factorization
| 2 | 680, 880, 232, 981 |
| 2 | 340, 440, 116, 981 |
| 2 | 170, 220, 58, 981 |
| 5 | 85, 110, 29, 981 |
| 17, 22, 29, 981 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 17 x 22 x 29 x 981 = 425597040
Therefore, the lowest common multiple of 680,880,232,981 is 425597040.
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.
680 x 880 x 232 x 981 = 136191052800
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
232 : 1, 2, 4, 8, 29, 58, 116, 232
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,880,232,981, is 1.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
880:2x 2x 2x 2x 5x 11
232:2x 2x 2x 29
981:3x 3x 109
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 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 136191052800/(1x320)
LCM = 136191052800/320
LCM = 425597040
Thus, we can understand that the LCM of 680,880,232,981 is 425597040.
