Given numbers are 488,516,518,642,747
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 488,516,518,642,747 is 434402605224.
Find LCM of 488,516,518,642,747 with Prime Factorization
| 2 | 488, 516, 518, 642, 747 |
| 2 | 244, 258, 259, 321, 747 |
| 3 | 122, 129, 259, 321, 747 |
| 122, 43, 259, 107, 249 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 122 x 43 x 259 x 107 x 249 = 434402605224
Therefore, the lowest common multiple of 488,516,518,642,747 is 434402605224.
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.
488 x 516 x 518 x 642 x 747 = 62553975152256
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.
488 : 1, 2, 4, 8, 61, 122, 244, 488
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
518 : 1, 2, 7, 14, 37, 74, 259, 518
642 : 1, 2, 3, 6, 107, 214, 321, 642
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 488,516,518,642,747, is 1.
Now, the common factors can be found like this.
488:2x 2x 2x 61
516:2x 2x 3x 43
518:2x 7x 37
642:2x 3x 107
747:3x 3x 83
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 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 62553975152256/(1x144)
LCM = 62553975152256/144
LCM = 434402605224
Thus, we can understand that the LCM of 488,516,518,642,747 is 434402605224.
