Given numbers are 978,856,764,824,496
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,856,764,824,496 is 510557787984.
Find LCM of 978,856,764,824,496 with Prime Factorization
| 2 | 978, 856, 764, 824, 496 |
| 2 | 489, 428, 382, 412, 248 |
| 2 | 489, 214, 191, 206, 124 |
| 489, 107, 191, 103, 62 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 489 x 107 x 191 x 103 x 62 = 510557787984
Therefore, the lowest common multiple of 978,856,764,824,496 is 510557787984.
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.
978 x 856 x 764 x 824 x 496 = 261405587447808
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
856 : 1, 2, 4, 8, 107, 214, 428, 856
764 : 1, 2, 4, 191, 382, 764
824 : 1, 2, 4, 8, 103, 206, 412, 824
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,856,764,824,496, is 2.
Now, the common factors can be found like this.
978:2x 3x 163
856:2x 2x 2x 107
764:2x 2x 191
824:2x 2x 2x 103
496:2x 2x 2x 2x 31
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 2x 2 = 256
Therefore, the value for common factors is 256.
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 = 261405587447808/(2x256)
LCM = 261405587447808/512
LCM = 510557787984
Thus, we can understand that the LCM of 978,856,764,824,496 is 510557787984.
