Given numbers are 201,551,998,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 201,551,998,285 is 552647490.
Find LCM of 201,551,998,285 with Prime Factorization
| 3 | 201, 551, 998, 285 |
| 19 | 67, 551, 998, 95 |
| 67, 29, 998, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 67 x 29 x 998 x 5 = 552647490
Therefore, the lowest common multiple of 201,551,998,285 is 552647490.
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.
201 x 551 x 998 x 285 = 31500906930
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.
201 : 1, 3, 67, 201
551 : 1, 19, 29, 551
998 : 1, 2, 499, 998
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 201,551,998,285, is 1.
Now, the common factors can be found like this.
201:3x 67
551:19x 29
998:2x 499
285:3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19 = 57
Therefore, the value for common factors is 57.
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 = 31500906930/(1x57)
LCM = 31500906930/57
LCM = 552647490
Thus, we can understand that the LCM of 201,551,998,285 is 552647490.
