Given numbers are 202,355,398,284
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 202,355,398,284 is 28540580.
Find LCM of 202,355,398,284 with Prime Factorization
| 2 | 202, 355, 398, 284 |
| 71 | 101, 355, 199, 142 |
| 101, 5, 199, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 71 x 101 x 5 x 199 x 2 = 28540580
Therefore, the lowest common multiple of 202,355,398,284 is 28540580.
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.
202 x 355 x 398 x 284 = 8105524720
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.
202 : 1, 2, 101, 202
355 : 1, 5, 71, 355
398 : 1, 2, 199, 398
284 : 1, 2, 4, 71, 142, 284
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 202,355,398,284, is 1.
Now, the common factors can be found like this.
202:2x 101
355:5x 71
398:2x 199
284:2x 2x 71
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 71 = 284
Therefore, the value for common factors is 284.
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 = 8105524720/(1x284)
LCM = 8105524720/284
LCM = 28540580
Thus, we can understand that the LCM of 202,355,398,284 is 28540580.
