Find LCM of 972,399,999,703 with Prime Factorization
| 3 | 972, 399, 999, 703 |
| 3 | 324, 133, 333, 703 |
| 3 | 108, 133, 111, 703 |
| 19 | 36, 133, 37, 703 |
| 37 | 36, 7, 37, 37 |
| 36, 7, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 19 x 37 x 36 x 7 x 1 x 1 = 4783212
Therefore, the lowest common multiple of 972,399,999,703 is 4783212.
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.
972 x 399 x 999 x 703 = 272370440916
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
399 : 1, 3, 7, 19, 21, 57, 133, 399
999 : 1, 3, 9, 27, 37, 111, 333, 999
703 : 1, 19, 37, 703
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,399,999,703, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
399:3x 7x 19
999:3x 3x 3x 37
703:19x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 19x 37 = 56943
Therefore, the value for common factors is 56943.
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 = 272370440916/(1x56943)
LCM = 272370440916/56943
LCM = 4783212
Thus, we can understand that the LCM of 972,399,999,703 is 4783212.
