The LCM of 285,824,999,740 is 78201720.
Find LCM of 285,824,999,740 with Prime Factorization
| 2 | 285, 824, 999, 740 |
| 2 | 285, 412, 999, 370 |
| 3 | 285, 206, 999, 185 |
| 5 | 95, 206, 333, 185 |
| 37 | 19, 206, 333, 37 |
| 19, 206, 9, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 37 x 19 x 206 x 9 x 1 = 78201720
Therefore, the lowest common multiple of 285,824,999,740 is 78201720.
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.
285 x 824 x 999 x 740 = 173607818400
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.
285 : 1, 3, 5, 15, 19, 57, 95, 285
824 : 1, 2, 4, 8, 103, 206, 412, 824
999 : 1, 3, 9, 27, 37, 111, 333, 999
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,824,999,740, is 1.
Now, the common factors can be found like this.
285:3x 5x 19
824:2x 2x 2x 103
999:3x 3x 3x 37
740:2x 2x 5x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 5x 37 = 2220
Therefore, the value for common factors is 2220.
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 = 173607818400/(1x2220)
LCM = 173607818400/2220
LCM = 78201720
Thus, we can understand that the LCM of 285,824,999,740 is 78201720.
