Given numbers are 966,605,904,722,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 966,605,904,722,646 is 1621164403320.
Find LCM of 966,605,904,722,646 with Prime Factorization
| 2 | 966, 605, 904, 722, 646 |
| 19 | 483, 605, 452, 361, 323 |
| 483, 605, 452, 19, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 483 x 605 x 452 x 19 x 17 = 1621164403320
Therefore, the lowest common multiple of 966,605,904,722,646 is 1621164403320.
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.
966 x 605 x 904 x 722 x 646 = 246416989304640
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.
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
605 : 1, 5, 11, 55, 121, 605
904 : 1, 2, 4, 8, 113, 226, 452, 904
722 : 1, 2, 19, 38, 361, 722
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 966,605,904,722,646, is 1.
Now, the common factors can be found like this.
966:2x 3x 7x 23
605:5x 11x 11
904:2x 2x 2x 113
722:2x 19x 19
646:2x 17x 19
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 19 = 152
Therefore, the value for common factors is 152.
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 = 246416989304640/(1x152)
LCM = 246416989304640/152
LCM = 1621164403320
Thus, we can understand that the LCM of 966,605,904,722,646 is 1621164403320.
