Given numbers are 777,568,444,129,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 777,568,444,129,842 is 7989505608.
Find LCM of 777,568,444,129,842 with Prime Factorization
| 2 | 777, 568, 444, 129, 842 |
| 2 | 777, 284, 222, 129, 421 |
| 3 | 777, 142, 111, 129, 421 |
| 37 | 259, 142, 37, 43, 421 |
| 7, 142, 1, 43, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 37 x 7 x 142 x 1 x 43 x 421 = 7989505608
Therefore, the lowest common multiple of 777,568,444,129,842 is 7989505608.
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 568 x 444 x 129 x 842 = 21284042939712
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
568 : 1, 2, 4, 8, 71, 142, 284, 568
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
129 : 1, 3, 43, 129
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 777,568,444,129,842, is 1.
Now, the common factors can be found like this.
777:3x 7x 37
568:2x 2x 2x 71
444:2x 2x 3x 37
129:3x 43
842:2x 421
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 37 = 2664
Therefore, the value for common factors is 2664.
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 = 21284042939712/(1x2664)
LCM = 21284042939712/2664
LCM = 7989505608
Thus, we can understand that the LCM of 777,568,444,129,842 is 7989505608.
