Given numbers are 669,671,831,218,744
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,671,831,218,744 is 3361294661736.
Find LCM of 669,671,831,218,744 with Prime Factorization
| 2 | 669, 671, 831, 218, 744 |
| 3 | 669, 671, 831, 109, 372 |
| 223, 671, 277, 109, 124 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 223 x 671 x 277 x 109 x 124 = 3361294661736
Therefore, the lowest common multiple of 669,671,831,218,744 is 3361294661736.
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.
669 x 671 x 831 x 218 x 744 = 60503303911248
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.
669 : 1, 3, 223, 669
671 : 1, 11, 61, 671
831 : 1, 3, 277, 831
218 : 1, 2, 109, 218
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,671,831,218,744, is 1.
Now, the common factors can be found like this.
669:3x 223
671:11x 61
831:3x 277
218:2x 109
744:2x 2x 2x 3x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 60503303911248/(1x18)
LCM = 60503303911248/18
LCM = 3361294661736
Thus, we can understand that the LCM of 669,671,831,218,744 is 3361294661736.
