Given numbers are 756,978,896,586
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 756,978,896,586 is 1155385728.
Find LCM of 756,978,896,586 with Prime Factorization
| 2 | 756, 978, 896, 586 |
| 2 | 378, 489, 448, 293 |
| 3 | 189, 489, 224, 293 |
| 7 | 63, 163, 224, 293 |
| 9, 163, 32, 293 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 9 x 163 x 32 x 293 = 1155385728
Therefore, the lowest common multiple of 756,978,896,586 is 1155385728.
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.
756 x 978 x 896 x 586 = 388209604608
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.
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
978 : 1, 2, 3, 6, 163, 326, 489, 978
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
586 : 1, 2, 293, 586
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,978,896,586, is 2.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
978:2x 3x 163
896:2x 2x 2x 2x 2x 2x 2x 7
586:2x 293
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 388209604608/(2x168)
LCM = 388209604608/336
LCM = 1155385728
Thus, we can understand that the LCM of 756,978,896,586 is 1155385728.
