Given numbers are 978,689,901,807
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,689,901,807 is 3081479466.
Find LCM of 978,689,901,807 with Prime Factorization
| 3 | 978, 689, 901, 807 |
| 53 | 326, 689, 901, 269 |
| 326, 13, 17, 269 |
Multiply the prime numbers at the bottom and the left side.
3 x 53 x 326 x 13 x 17 x 269 = 3081479466
Therefore, the lowest common multiple of 978,689,901,807 is 3081479466.
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 689 x 901 x 807 = 489955235094
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
689 : 1, 13, 53, 689
901 : 1, 17, 53, 901
807 : 1, 3, 269, 807
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,689,901,807, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
689:13x 53
901:17x 53
807:3x 269
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 53 = 159
Therefore, the value for common factors is 159.
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 = 489955235094/(1x159)
LCM = 489955235094/159
LCM = 3081479466
Thus, we can understand that the LCM of 978,689,901,807 is 3081479466.
