Given numbers are 389,202,284,340,213
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 389,202,284,340,213 is 2845309380.
Find LCM of 389,202,284,340,213 with Prime Factorization
| 2 | 389, 202, 284, 340, 213 |
| 2 | 389, 101, 142, 170, 213 |
| 71 | 389, 101, 71, 85, 213 |
| 389, 101, 1, 85, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 71 x 389 x 101 x 1 x 85 x 3 = 2845309380
Therefore, the lowest common multiple of 389,202,284,340,213 is 2845309380.
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.
389 x 202 x 284 x 340 x 213 = 1616135727840
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.
389 : 1, 389
202 : 1, 2, 101, 202
284 : 1, 2, 4, 71, 142, 284
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
213 : 1, 3, 71, 213
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,202,284,340,213, is 1.
Now, the common factors can be found like this.
389:389
202:2x 101
284:2x 2x 71
340:2x 2x 5x 17
213:3x 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 2x 71 = 568
Therefore, the value for common factors is 568.
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 = 1616135727840/(1x568)
LCM = 1616135727840/568
LCM = 2845309380
Thus, we can understand that the LCM of 389,202,284,340,213 is 2845309380.
