The LCM of 143,957,455,435 is 435435.
Find LCM of 143,957,455,435 with Prime Factorization
| 3 | 143, 957, 455, 435 |
| 5 | 143, 319, 455, 145 |
| 11 | 143, 319, 91, 29 |
| 13 | 13, 29, 91, 29 |
| 29 | 1, 29, 7, 29 |
| 1, 1, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 13 x 29 x 1 x 1 x 7 x 1 = 435435
Therefore, the lowest common multiple of 143,957,455,435 is 435435.
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.
143 x 957 x 455 x 435 = 27086234175
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.
143 : 1, 11, 13, 143
957 : 1, 3, 11, 29, 33, 87, 319, 957
455 : 1, 5, 7, 13, 35, 65, 91, 455
435 : 1, 3, 5, 15, 29, 87, 145, 435
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,957,455,435, is 1.
Now, the common factors can be found like this.
143:11x 13
957:3x 11x 29
455:5x 7x 13
435:3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11x 13x 29 = 62205
Therefore, the value for common factors is 62205.
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 = 27086234175/(1x62205)
LCM = 27086234175/62205
LCM = 435435
Thus, we can understand that the LCM of 143,957,455,435 is 435435.
