The LCM of 435,981,288,756 is 95588640.
Find LCM of 435,981,288,756 with Prime Factorization
| 2 | 435, 981, 288, 756 |
| 2 | 435, 981, 144, 378 |
| 3 | 435, 981, 72, 189 |
| 3 | 145, 327, 24, 63 |
| 145, 109, 8, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 145 x 109 x 8 x 21 = 95588640
Therefore, the lowest common multiple of 435,981,288,756 is 95588640.
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.
435 x 981 x 288 x 756 = 92912158080
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.
435 : 1, 3, 5, 15, 29, 87, 145, 435
981 : 1, 3, 9, 109, 327, 981
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 435,981,288,756, is 3.
Now, the common factors can be found like this.
435:3x 5x 29
981:3x 3x 109
288:2x 2x 2x 2x 2x 3x 3
756:2x 2x 3x 3x 3x 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 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 92912158080/(3x324)
LCM = 92912158080/972
LCM = 95588640
Thus, we can understand that the LCM of 435,981,288,756 is 95588640.
