The LCM of 260,285,992,942 is 577031520.
Find LCM of 260,285,992,942 with Prime Factorization
| 2 | 260, 285, 992, 942 |
| 2 | 130, 285, 496, 471 |
| 3 | 65, 285, 248, 471 |
| 5 | 65, 95, 248, 157 |
| 13, 19, 248, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 19 x 248 x 157 = 577031520
Therefore, the lowest common multiple of 260,285,992,942 is 577031520.
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.
260 x 285 x 992 x 942 = 69243782400
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.
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
285 : 1, 3, 5, 15, 19, 57, 95, 285
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 260,285,992,942, is 1.
Now, the common factors can be found like this.
260:2x 2x 5x 13
285:3x 5x 19
992:2x 2x 2x 2x 2x 31
942:2x 3x 157
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 2x 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 69243782400/(1x120)
LCM = 69243782400/120
LCM = 577031520
Thus, we can understand that the LCM of 260,285,992,942 is 577031520.
