The LCM of 669,297,374,646,869 is 3380032854.
Find LCM of 669,297,374,646,869 with Prime Factorization
| 2 | 669, 297, 374, 646, 869 |
| 3 | 669, 297, 187, 323, 869 |
| 11 | 223, 99, 187, 323, 869 |
| 17 | 223, 9, 17, 323, 79 |
| 223, 9, 1, 19, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 223 x 9 x 1 x 19 x 79 = 3380032854
Therefore, the lowest common multiple of 669,297,374,646,869 is 3380032854.
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 297 x 374 x 646 x 869 = 41716365484068
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
297 : 1, 3, 9, 11, 27, 33, 99, 297
374 : 1, 2, 11, 17, 22, 34, 187, 374
646 : 1, 2, 17, 19, 34, 38, 323, 646
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,297,374,646,869, is 1.
Now, the common factors can be found like this.
669:3x 223
297:3x 3x 3x 11
374:2x 11x 17
646:2x 17x 19
869:11x 79
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 11x 11x 17 = 12342
Therefore, the value for common factors is 12342.
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 = 41716365484068/(1x12342)
LCM = 41716365484068/12342
LCM = 3380032854
Thus, we can understand that the LCM of 669,297,374,646,869 is 3380032854.
