Given numbers are 487,627,703,440
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 487,627,703,440 is 451916520.
Find LCM of 487,627,703,440 with Prime Factorization
| 11 | 487, 627, 703, 440 |
| 19 | 487, 57, 703, 40 |
| 487, 3, 37, 40 |
Multiply the prime numbers at the bottom and the left side.
11 x 19 x 487 x 3 x 37 x 40 = 451916520
Therefore, the lowest common multiple of 487,627,703,440 is 451916520.
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.
487 x 627 x 703 x 440 = 94450552680
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.
487 : 1, 487
627 : 1, 3, 11, 19, 33, 57, 209, 627
703 : 1, 19, 37, 703
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,627,703,440, is 1.
Now, the common factors can be found like this.
487:487
627:3x 11x 19
703:19x 37
440:2x 2x 2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 19 = 209
Therefore, the value for common factors is 209.
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 = 94450552680/(1x209)
LCM = 94450552680/209
LCM = 451916520
Thus, we can understand that the LCM of 487,627,703,440 is 451916520.
