Given numbers are 298,985,979,445
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 298,985,979,445 is 287365870.
Find LCM of 298,985,979,445 with Prime Factorization
5 | 298, 985, 979, 445 |
89 | 298, 197, 979, 89 |
298, 197, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 89 x 298 x 197 x 11 x 1 = 287365870
Therefore, the lowest common multiple of 298,985,979,445 is 287365870.
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.
298 x 985 x 979 x 445 = 127877812150
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.
298 : 1, 2, 149, 298
985 : 1, 5, 197, 985
979 : 1, 11, 89, 979
445 : 1, 5, 89, 445
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 298,985,979,445, is 1.
Now, the common factors can be found like this.
298:2x 149
985:5x 197
979:11x 89
445:5x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 89 = 445
Therefore, the value for common factors is 445.
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 = 127877812150/(1x445)
LCM = 127877812150/445
LCM = 287365870
Thus, we can understand that the LCM of 298,985,979,445 is 287365870.
