Given numbers are 990,303,917,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 990,303,917,715 is 1191980790.
Find LCM of 990,303,917,715 with Prime Factorization
3 | 990, 303, 917, 715 |
5 | 330, 101, 917, 715 |
11 | 66, 101, 917, 143 |
6, 101, 917, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 6 x 101 x 917 x 13 = 1191980790
Therefore, the lowest common multiple of 990,303,917,715 is 1191980790.
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.
990 x 303 x 917 x 715 = 196676830350
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.
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
303 : 1, 3, 101, 303
917 : 1, 7, 131, 917
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,303,917,715, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
303:3x 101
917:7x 131
715:5x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 196676830350/(1x165)
LCM = 196676830350/165
LCM = 1191980790
Thus, we can understand that the LCM of 990,303,917,715 is 1191980790.
