The LCM of 732,407,792,989 is 1767881016.
Find LCM of 732,407,792,989 with Prime Factorization
| 2 | 732, 407, 792, 989 |
| 2 | 366, 407, 396, 989 |
| 3 | 183, 407, 198, 989 |
| 11 | 61, 407, 66, 989 |
| 61, 37, 6, 989 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 61 x 37 x 6 x 989 = 1767881016
Therefore, the lowest common multiple of 732,407,792,989 is 1767881016.
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.
732 x 407 x 792 x 989 = 233360294112
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.
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
407 : 1, 11, 37, 407
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 732,407,792,989, is 1.
Now, the common factors can be found like this.
732:2x 2x 3x 61
407:11x 37
792:2x 2x 2x 3x 3x 11
989:23x 43
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 11 = 132
Therefore, the value for common factors is 132.
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 = 233360294112/(1x132)
LCM = 233360294112/132
LCM = 1767881016
Thus, we can understand that the LCM of 732,407,792,989 is 1767881016.
