Given numbers are 285,957,386,518,981
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 285,957,386,518,981 is 2972147540670.
Find LCM of 285,957,386,518,981 with Prime Factorization
| 2 | 285, 957, 386, 518, 981 |
| 3 | 285, 957, 193, 259, 981 |
| 95, 319, 193, 259, 327 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 95 x 319 x 193 x 259 x 327 = 2972147540670
Therefore, the lowest common multiple of 285,957,386,518,981 is 2972147540670.
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 957 x 386 x 518 x 981 = 53498655732060
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
957 : 1, 3, 11, 29, 33, 87, 319, 957
386 : 1, 2, 193, 386
518 : 1, 2, 7, 14, 37, 74, 259, 518
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,957,386,518,981, is 1.
Now, the common factors can be found like this.
285:3x 5x 19
957:3x 11x 29
386:2x 193
518:2x 7x 37
981:3x 3x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 53498655732060/(1x18)
LCM = 53498655732060/18
LCM = 2972147540670
Thus, we can understand that the LCM of 285,957,386,518,981 is 2972147540670.
