Given numbers are 978,608,949,104
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,608,949,104 is 282149088.
Find LCM of 978,608,949,104 with Prime Factorization
| 2 | 978, 608, 949, 104 |
| 2 | 489, 304, 949, 52 |
| 2 | 489, 152, 949, 26 |
| 13 | 489, 76, 949, 13 |
| 489, 76, 73, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 489 x 76 x 73 x 1 = 282149088
Therefore, the lowest common multiple of 978,608,949,104 is 282149088.
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 608 x 949 x 104 = 58687010304
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
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
949 : 1, 13, 73, 949
104 : 1, 2, 4, 8, 13, 26, 52, 104
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,608,949,104, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
608:2x 2x 2x 2x 2x 19
949:13x 73
104:2x 2x 2x 13
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 13 = 208
Therefore, the value for common factors is 208.
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 = 58687010304/(1x208)
LCM = 58687010304/208
LCM = 282149088
Thus, we can understand that the LCM of 978,608,949,104 is 282149088.
