Given numbers are 447,978,839,917
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 447,978,839,917 is 112113115086.
Find LCM of 447,978,839,917 with Prime Factorization
3 | 447, 978, 839, 917 |
149, 326, 839, 917 |
Multiply the prime numbers at the bottom and the left side.
3 x 149 x 326 x 839 x 917 = 112113115086
Therefore, the lowest common multiple of 447,978,839,917 is 112113115086.
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.
447 x 978 x 839 x 917 = 336339345258
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.
447 : 1, 3, 149, 447
978 : 1, 2, 3, 6, 163, 326, 489, 978
839 : 1, 839
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,978,839,917, is 1.
Now, the common factors can be found like this.
447:3x 149
978:2x 3x 163
839:839
917:7x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 336339345258/(1x3)
LCM = 336339345258/3
LCM = 112113115086
Thus, we can understand that the LCM of 447,978,839,917 is 112113115086.
