Given numbers are 290,102,212,389,140
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 290,102,212,389,140 is 4268956020.
Find LCM of 290,102,212,389,140 with Prime Factorization
| 2 | 290, 102, 212, 389, 140 |
| 2 | 145, 51, 106, 389, 70 |
| 5 | 145, 51, 53, 389, 35 |
| 29, 51, 53, 389, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 29 x 51 x 53 x 389 x 7 = 4268956020
Therefore, the lowest common multiple of 290,102,212,389,140 is 4268956020.
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.
290 x 102 x 212 x 389 x 140 = 341516481600
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.
290 : 1, 2, 5, 10, 29, 58, 145, 290
102 : 1, 2, 3, 6, 17, 34, 51, 102
212 : 1, 2, 4, 53, 106, 212
389 : 1, 389
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,102,212,389,140, is 1.
Now, the common factors can be found like this.
290:2x 5x 29
102:2x 3x 17
212:2x 2x 53
389:389
140:2x 2x 5x 7
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 2x 5 = 80
Therefore, the value for common factors is 80.
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 = 341516481600/(1x80)
LCM = 341516481600/80
LCM = 4268956020
Thus, we can understand that the LCM of 290,102,212,389,140 is 4268956020.
