Find LCM of 664,504,621,433,909 with Prime Factorization
| 2 | 664, 504, 621, 433, 909 |
| 2 | 332, 252, 621, 433, 909 |
| 2 | 166, 126, 621, 433, 909 |
| 3 | 83, 63, 621, 433, 909 |
| 3 | 83, 21, 207, 433, 303 |
| 83, 7, 69, 433, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 83 x 7 x 69 x 433 x 101 = 126231281064
Therefore, the lowest common multiple of 664,504,621,433,909 is 126231281064.
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.
664 x 504 x 621 x 433 x 909 = 81797870129472
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.
664 : 1, 2, 4, 8, 83, 166, 332, 664
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
621 : 1, 3, 9, 23, 27, 69, 207, 621
433 : 1, 433
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,504,621,433,909, is 1.
Now, the common factors can be found like this.
664:2x 2x 2x 83
504:2x 2x 2x 3x 3x 7
621:3x 3x 3x 23
433:433
909:3x 3x 101
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 3x 3 = 648
Therefore, the value for common factors is 648.
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 = 81797870129472/(1x648)
LCM = 81797870129472/648
LCM = 126231281064
Thus, we can understand that the LCM of 664,504,621,433,909 is 126231281064.
