Given numbers are 777,642,276,524,993
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 777,642,276,524,993 is 331659096468.
Find LCM of 777,642,276,524,993 with Prime Factorization
| 2 | 777, 642, 276, 524, 993 |
| 2 | 777, 321, 138, 262, 993 |
| 3 | 777, 321, 69, 131, 993 |
| 259, 107, 23, 131, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 259 x 107 x 23 x 131 x 331 = 331659096468
Therefore, the lowest common multiple of 777,642,276,524,993 is 331659096468.
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.
777 x 642 x 276 x 524 x 993 = 71638364837088
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.
777 : 1, 3, 7, 21, 37, 111, 259, 777
642 : 1, 2, 3, 6, 107, 214, 321, 642
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
524 : 1, 2, 4, 131, 262, 524
993 : 1, 3, 331, 993
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,642,276,524,993, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
642:2x 3x 107
276:2x 2x 3x 23
524:2x 2x 131
993:3x 331
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 71638364837088/(1x216)
LCM = 71638364837088/216
LCM = 331659096468
Thus, we can understand that the LCM of 777,642,276,524,993 is 331659096468.
