The LCM of 451,120,869,540 is 38479320.
Find LCM of 451,120,869,540 with Prime Factorization
| 2 | 451, 120, 869, 540 |
| 2 | 451, 60, 869, 270 |
| 3 | 451, 30, 869, 135 |
| 5 | 451, 10, 869, 45 |
| 11 | 451, 2, 869, 9 |
| 41, 2, 79, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 41 x 2 x 79 x 9 = 38479320
Therefore, the lowest common multiple of 451,120,869,540 is 38479320.
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.
451 x 120 x 869 x 540 = 25396351200
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.
451 : 1, 11, 41, 451
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
869 : 1, 11, 79, 869
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,120,869,540, is 1.
Now, the common factors can be found like this.
451:11x 41
120:2x 2x 2x 3x 5
869:11x 79
540:2x 2x 3x 3x 3x 5
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 3x 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 25396351200/(1x660)
LCM = 25396351200/660
LCM = 38479320
Thus, we can understand that the LCM of 451,120,869,540 is 38479320.
