Given numbers are 687,534,240,532,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,534,240,532,986 is 320726829360.
Find LCM of 687,534,240,532,986 with Prime Factorization
| 2 | 687, 534, 240, 532, 986 |
| 2 | 687, 267, 120, 266, 493 |
| 3 | 687, 267, 60, 133, 493 |
| 229, 89, 20, 133, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 229 x 89 x 20 x 133 x 493 = 320726829360
Therefore, the lowest common multiple of 687,534,240,532,986 is 320726829360.
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.
687 x 534 x 240 x 532 x 986 = 46184663427840
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.
687 : 1, 3, 229, 687
534 : 1, 2, 3, 6, 89, 178, 267, 534
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,534,240,532,986, is 1.
Now, the common factors can be found like this.
687:3x 229
534:2x 3x 89
240:2x 2x 2x 2x 3x 5
532:2x 2x 7x 19
986:2x 17x 29
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 = 46184663427840/(1x144)
LCM = 46184663427840/144
LCM = 320726829360
Thus, we can understand that the LCM of 687,534,240,532,986 is 320726829360.
