The LCM of 760,418,120,287 is 7197960.
Find LCM of 760,418,120,287 with Prime Factorization
| 2 | 760, 418, 120, 287 |
| 2 | 380, 209, 60, 287 |
| 2 | 190, 209, 30, 287 |
| 5 | 95, 209, 15, 287 |
| 19 | 19, 209, 3, 287 |
| 1, 11, 3, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 19 x 1 x 11 x 3 x 287 = 7197960
Therefore, the lowest common multiple of 760,418,120,287 is 7197960.
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.
760 x 418 x 120 x 287 = 10940899200
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.
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
418 : 1, 2, 11, 19, 22, 38, 209, 418
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,418,120,287, is 1.
Now, the common factors can be found like this.
760:2x 2x 2x 5x 19
418:2x 11x 19
120:2x 2x 2x 3x 5
287:7x 41
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 5x 19 = 1520
Therefore, the value for common factors is 1520.
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 = 10940899200/(1x1520)
LCM = 10940899200/1520
LCM = 7197960
Thus, we can understand that the LCM of 760,418,120,287 is 7197960.
