Given numbers are 975,891,117,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 975,891,117,285 is 5501925.
Find LCM of 975,891,117,285 with Prime Factorization
3 | 975, 891, 117, 285 |
3 | 325, 297, 39, 95 |
5 | 325, 99, 13, 95 |
13 | 65, 99, 13, 19 |
5, 99, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 13 x 5 x 99 x 1 x 19 = 5501925
Therefore, the lowest common multiple of 975,891,117,285 is 5501925.
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.
975 x 891 x 117 x 285 = 28967635125
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.
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
117 : 1, 3, 9, 13, 39, 117
285 : 1, 3, 5, 15, 19, 57, 95, 285
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 975,891,117,285, is 3.
Now, the common factors can be found like this.
975:3x 5x 5x 13
891:3x 3x 3x 3x 11
117:3x 3x 13
285:3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 13 = 1755
Therefore, the value for common factors is 1755.
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 = 28967635125/(3x1755)
LCM = 28967635125/5265
LCM = 5501925
Thus, we can understand that the LCM of 975,891,117,285 is 5501925.
