The LCM of 669,646,414,966 is 208740042.
Find LCM of 669,646,414,966 with Prime Factorization
| 2 | 669, 646, 414, 966 |
| 3 | 669, 323, 207, 483 |
| 23 | 223, 323, 69, 161 |
| 223, 323, 3, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 223 x 323 x 3 x 7 = 208740042
Therefore, the lowest common multiple of 669,646,414,966 is 208740042.
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 646 x 414 x 966 = 172836754776
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
646 : 1, 2, 17, 19, 34, 38, 323, 646
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,646,414,966, is 1.
Now, the common factors can be found like this.
669:3x 223
646:2x 17x 19
414:2x 3x 3x 23
966:2x 3x 7x 23
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 3x 3x 23 = 828
Therefore, the value for common factors is 828.
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 = 172836754776/(1x828)
LCM = 172836754776/828
LCM = 208740042
Thus, we can understand that the LCM of 669,646,414,966 is 208740042.
