Given numbers are 508,722,990,286
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 508,722,990,286 is 1180101780.
Find LCM of 508,722,990,286 with Prime Factorization
| 2 | 508, 722, 990, 286 |
| 11 | 254, 361, 495, 143 |
| 254, 361, 45, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 254 x 361 x 45 x 13 = 1180101780
Therefore, the lowest common multiple of 508,722,990,286 is 1180101780.
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.
508 x 722 x 990 x 286 = 103848956640
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.
508 : 1, 2, 4, 127, 254, 508
722 : 1, 2, 19, 38, 361, 722
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
286 : 1, 2, 11, 13, 22, 26, 143, 286
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 508,722,990,286, is 2.
Now, the common factors can be found like this.
508:2x 2x 127
722:2x 19x 19
990:2x 3x 3x 5x 11
286:2x 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.
2x 2x 11 = 44
Therefore, the value for common factors is 44.
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 = 103848956640/(2x44)
LCM = 103848956640/88
LCM = 1180101780
Thus, we can understand that the LCM of 508,722,990,286 is 1180101780.
